Question

What is the volume of this right prism?

1200 in3
1800 in3
2040 in3
3600 in3

Answer 1

2nd option

Explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h is its height )

A =
`(1)/(2)` bh ( b is the base and h the height )

here b = 30, h = 8 , then

A =
`(1)/(2)` × 30 × 8 = 15 × 8 = 120 in²

with h = 15 , then

V = 120 × 15 = 1800 in³
