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?

WITCHER [35]

Answer:

option C. $V=1,980\ yd^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}Bh$

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

$V=\frac{1}{3}(330)(18)=1,980\ yd^{3}$
