Question 1:

Shape Description:
The figure has two triangular bases (at the front and back) and three rectangular faces connecting them. The dimensions are labeled as 3 cm, 4 cm, and 11 cm.

- Analysis:
- A triangular prism has two congruent triangular bases and three rectangular lateral faces.
- This matches the given shape perfectly.

✔ Correct Answer: C) Triangular Prism

Question 2:

Shape Description:
A box-like shape with six rectangular faces — all edges are straight, and it appears to have a rectangular base.

- Analysis:
- A rectangular prism has 6 faces, all rectangles (or squares), and opposite faces are equal.
- This is a classic example of a rectangular prism (also known as a cuboid).

✔ Correct Answer: B) Rectangular Prism

Question 3:

Shape Description:
A pyramid with a triangular base (7 cm and 8 cm sides shown) and a height of 12 cm. It has four triangular faces meeting at a single apex.

- Analysis:
- A triangular pyramid (also called a tetrahedron) has a triangular base and three triangular faces that meet at a point.
- Since the base is a triangle and the top is a point, this is a triangular pyramid.

✔ Correct Answer: B) Triangular Pyramid

Question 4:

Shape Description:
A pyramid with a square base and four triangular faces converging at a single apex.

- Analysis:
- A square pyramid has a square base and four triangular faces.
- The shape clearly shows a square at the bottom and triangles going up to a point.

✔ Correct Answer: B) Square Pyramid
