Question

What is the volume of this square pyramid?

1296 cm³

1620 cm³

3888 cm³

11,664 cm³

Answer 1

Answer: 1296 cm³

Explanation:

Since, the volume of a square pyramid is,

`V = (a^2h)/(3)`

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

`V = (18^2* 12)/(3)`

`= (324* 12)/(3)`

`=(3888)/(3)`

`=1296` cube cm.

⇒ First option is correct.
