Question

A triangular pyramid has a height of 18 yards and a base with an area of 330 square yards. What is the volume of the pyramid?

A. 660 yd
B. 2,970 yd
C. 1,980 yd
D. 5,940 yd

Answer 1

option C.
`V=1,980\ yd^(3)`

Explanation:

we know that

The volume of the triangular pyramid is equal to

`V=(1)/(3)Bh`

where

B is the area of the triangular base

h is the height of the pyramid

In this problem we have

`B=330\ yd^(2)`

`h=18\ yd`

substitute in the formula

`V=(1)/(3)(330)(18)=1,980\ yd^(3)`
