Pls help!!!

Answer 1

Answer:

The height of the pyramid is $50\ in$

Step-by-step explanation:

we know that

The volume of a triangular pyramid is equal to

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

where

B is the area of the base

H is the height of the pyramid

we have

$V=1,800\ in^{3}$

The area of the base B is equal to

$B=\frac{1}{2}(12)(18)=108\ in^{2}$

substitute and solve for H

$1,800=\frac{1}{3}(108)H$

$5,400=(108)H$

$H=5,400/(108)=50\ in$
