Question

What is the volume of a triangular prism whose triangular face has a base of 15 in., height of 3 in., and the height of the prism is16 in.? A. 720 in3 B. 240 in3 C. 243 in3 D. 360 in3

Answer 1

we know that

[volume of the triangular prism]=[area of the base]*height

area of the base=15*3/2-----> 22.5 in²
height of the prism=16 in
so
[volume of the triangular prism]=[22.5]*16------> 360 in³

the answer is
the volume of the triangular prism is 360 in³
