Find the volume of square pyramid with a base length of 9 cm and a height of 4 cm

1. 324 cm3
2. 108 cm3
3. 36 cm3
4. 152 cm3

1 answer

The correct answer is 108 cm3.

The formula for the volume of a square pyramid is:

V = (1/3) * base area * height

Since the base is a square with a length of 9 cm, the base area is:

base area = 9 cm * 9 cm = 81 cm2

Plugging in the given values:

V = (1/3) * 81 cm2 * 4 cm = 108 cm3
