Question

What is the volume of the square-based pyramid below?

a) 840
b) 420
c) 435
d) 100

Answer 1

d

Explanation:

the volume (V) of a pyramid is calculated as

V =
`(1)/(3)` Ah ( A is the area of the base and h the perpendicular height

here h = 12 and

A = 5 × 5 = 25 cm² , then

V =
`(1)/(3)` × 25 × 12 =
`(1)/(3)` × 300 = 100 cm³
