Answer:
The height is 50 inches
Step-by-step explanation:
Volume for a triangular pyramid is
V = 1/3 BH
where b is the base
Since this is a triangle, we use 1/2 b*h . We are given the base and the height of the triangle
B = 1/2 *12*18
B = 108
Using the formula for volume
V = 1/3 *108 *H
1800 = 36H
Divide each side by 36
1800/36 = 36H/36
50 = H
