Question

What is the volume of the pyramid in the diagram?

Answer 1

Option A:

Volume of the pyramid = 25 cm³

Solution:

To find the volume of the pyramid:

Base area = length × width

                 = 5 cm × 5 cm

Base area = 25 cm²

Perpendicular height of the pyramid = 3 cm

Volume of the pyramid = $\frac{1}{3} \times \text{base area}\times \text{perpendicular height}$

                                       $=\frac{1}{3}\times25 \times 3$

                                       = 25 cm³

Volume of the pyramid = 25 cm³

Hence option A is the correct answer.
