Let’s go through each question one by one and figure out the correct 3D shape names.
---
Question 1:
The shape shown has two triangular bases (top and bottom) and three rectangular sides connecting them. That’s the definition of a
triangular prism.
- A pyramid has one base and triangular faces that meet at a point.
- A rectangular pyramid has a rectangle base and triangular sides meeting at a point — not this.
- A triangular pyramid has a triangle base and three triangular sides meeting at a point — also not this.
✔ So, correct answer:
C. Triangular Prism
---
Question 2:
This is a box-shaped figure with six rectangular faces. All angles are right angles, and opposite faces are equal.
- A rectangular pyramid would have a rectangle base and triangular sides going up to a point — no.
- A square pyramid has a square base and four triangular sides — no.
- A rectangular prism is exactly what this is — a 3D box made of rectangles.
✔ So, correct answer:
B. Rectangular Prism
---
Question 3:
This shape has a rectangular base (7 cm by 8 cm) and four triangular faces that meet at a single top point. That’s a
rectangular pyramid.
- A triangular pyramid would have a triangle base — not this.
- A rectangular prism would have flat rectangular sides all around — no pointed top.
✔ So, correct answer:
A. Rectangular Pyramid
---
Question 4:
This shape has a square base (you can see four equal sides on the bottom) and four triangular faces rising to meet at a single top point. That’s a
square pyramid.
- A triangular prism has two triangle bases and three rectangles — not this.
- A square pyramid matches perfectly.
✔ So, correct answer:
B. Square Pyramid
---
Final Answer:
1. C
2. B
3. A
4. B
