3d Shapes Worksheets - Free Printable

Let’s go step by step to identify each 3D shape and count its faces.

---

First row, left shape:
- It has a triangular base and three triangular sides meeting at a point.
- That’s a triangular based pyramid (also called a tetrahedron).
- Faces: 4 (1 base + 3 sides)

Wait — looking again: actually, this shape is drawn with two triangles on the front and back, and three rectangular sides? No — let me check carefully.

Actually, no — in the image, the first shape is a triangular prism? Wait — let’s look at the structure:

It has:
- Two triangular bases (front and back)
- Three rectangular sides connecting them

That makes it a triangular prism.

Faces: 5 (2 triangles + 3 rectangles)

But wait — the shaded part shows one triangle and one rectangle? Hmm.

Actually, let’s use standard definitions:

✔ Triangular Prism:
- 2 triangular faces (bases)
- 3 rectangular faces (sides)
→ Total = 5 faces

But in the diagram, the first shape looks like a triangular bipyramid? No — it's drawn as a prism lying on its side.

Looking at the answer bank provided in red text below: “Triangular prism” is listed — so likely that’s what they want for the first one.

Wait — let’s match all shapes to the answer bank:

Answer bank says:
- Triangular prism
- Cuboid
- Cylinder
- Square based pyramid
- Triangular based pyramid
- Cube

Now let’s assign:

---

Top Row:

1. First shape (left):
- Has two triangular ends and three rectangular sides → Triangular prism
→ Faces: 5

2. Middle shape:
- Looks like a box with rectangular faces — not necessarily square → Cuboid
→ Faces: 6

3. Right shape:
- Round tube with flat circular ends → Cylinder
→ Faces: 3 (2 circles + 1 curved surface — but in elementary math, sometimes they count only flat faces? Wait — important!)

️ Important note: In many school curricula, when counting “faces” of 3D shapes, they mean flat surfaces only.

So for cylinder:
- Flat faces: top circle and bottom circle → 2 faces
- Curved surface is NOT counted as a “face” in some contexts.

BUT — in other contexts, especially higher grades, curved surfaces are included.

Looking at the worksheet level (Grade 2 logo), and common UK/US elementary standards:

In Grade 2–4, often:
- Cylinder: 2 flat faces + 1 curved surface → but if question says “faces”, they may mean only flat ones.

Wait — let’s check the answer bank and typical expectations.

Actually, let’s look at the last shape in bottom right: square-based pyramid — that has 5 faces (1 square base + 4 triangles).

And cube has 6.

Let me reassign based on visual matching:

---

Let’s label positions:

Row 1:
A: Left — triangular prism? Or tetrahedron?

Actually, looking closely: Shape A has 4 triangular faces? No — it’s drawn with 3 visible faces: one triangle, one quadrilateral, another triangle? I think it’s a triangular bipyramid? But that’s advanced.

Wait — perhaps it’s simpler.

Standard interpretation for such worksheets:

Shape 1 (top left): Triangular Prism — because it has two parallel triangular bases and three rectangular lateral faces → total 5 faces.

Shape 2 (top middle): Cube? Or cuboid? The shading suggests it’s a cube? But it’s drawn slightly skewed. However, since “cube” and “cuboid” are both in answer bank, we need to distinguish.

The top middle shape: all faces appear equal? Not necessarily — in drawing, it might be intended as a cuboid (rectangular prism). But if all edges equal, it’s a cube.

Given that “cube” is also an option, and there’s a separate “cuboid”, likely:

Top middle: Cuboid → 6 faces

Bottom middle: that’s clearly a triangular prism lying on its side? Wait no — bottom middle is a wedge — that’s a triangular prism too? Confusion.

Let me list all six shapes with correct identification:

---

After careful analysis using standard elementary geometry:

Top Row:

1. Left: Triangular Prism
- 2 triangular bases + 3 rectangular sides → 5 faces

2. Middle: Cuboid (rectangular prism)
- 6 rectangular faces → 6 faces

3. Right: Cylinder
- 2 flat circular faces + 1 curved surface → BUT in most elementary sheets, “faces” means flat surfaces only → so 2 faces
*(However, some sources say 3 — including curved. Let’s see context.)*

Wait — the answer bank includes “cylinder”, and typically in such worksheets, cylinder is said to have 3 faces: 2 flat + 1 curved. For example, NCERT or Common Core often teaches:

> Cylinder: 3 faces (2 flat, 1 curved)

Similarly, cone: 2 faces (1 flat, 1 curved)

Sphere: 0 or 1? Usually 0 flat faces.

So for consistency, we’ll go with:

Cylinder: 3 faces

---

Bottom Row:

4. Left: This is a rhombic prism? No — it’s a square-based prism? Actually, it’s a cube? No — angles suggest it’s a parallelepiped, but likely intended as cuboid again? Wait — no.

Actually, this shape is a hexagonal prism? No — it has 6 faces? Let’s count:

Visible: front face (parallelogram), top (shaded parallelogram), side... Actually, this is a prism with rhombus base? Too complex.

Wait — better approach: match to answer bank.

Answer bank has:

- Triangular prism → already used?
- Cuboid → used?
- Cylinder → used
- Square based pyramid
- Triangular based pyramid
- Cube

So remaining: square based pyramid, triangular based pyramid, cube

Look at bottom row:

Left: This is a cube? Drawn in perspective — yes! All faces are squares, just rotated. So Cube → 6 faces

Middle: This is a triangular prism lying on its triangular face? Yes — it has two triangular bases and three rectangular sides → Triangular Prism → 5 faces

Right: This is a square-based pyramid — square base, four triangular sides → 5 faces

Wait — but then we have two triangular prisms? And no “triangular based pyramid”?

Problem: We have 6 shapes and 6 names in answer bank.

List of shapes from image (by position):

1. Top-left: appears to be a tetrahedron? Or triangular bipyramid? Actually, upon closer inspection — it has 4 triangular faces → that’s a triangular based pyramid (tetrahedron) → 4 faces

Ah! That makes sense.

Let me redefine:

✔ Correct Identification:

Top Row:

1. Left: Triangular Based Pyramid (tetrahedron)
- 4 triangular faces → 4 faces

2. Middle: Cuboid
- 6 rectangular faces → 6 faces

3. Right: Cylinder
- 2 flat + 1 curved → 3 faces (standard in elementary)

Bottom Row:

4. Left: Cube
- 6 square faces → 6 faces

5. Middle: Triangular Prism
- 2 triangular + 3 rectangular → 5 faces

6. Right: Square Based Pyramid
- 1 square + 4 triangular → 5 faces

Now check against answer bank:

Answer bank lists:
- Triangular prism → matches #5
- Cuboid → #2
- Cylinder → #3
- Square based pyramid → #6
- Triangular based pyramid → #1
- Cube → #4

Perfect match!

Now confirm face counts:

1. Triangular based pyramid: 4 faces ✔️
2. Cuboid: 6 faces ✔️
3. Cylinder: 3 faces (including curved) ✔️
4. Cube: 6 faces ✔️
5. Triangular prism: 5 faces ✔️
6. Square based pyramid: 5 faces ✔️

All consistent.
