Question

A right triangular prism has bases that are isosceles triangles. One triangular base is 12 centimeters long by 8 centimeters high. The height of the prism is 20 centimeters. What is the volume of the prism?

Answer 1

960 cm^3

Explanation:

volume of prism = area of base * height

The base is a triangle, so its area is bh/2

area of base = (12 cm)(8 cm)/2

area of base = 48 cm^2

volume of prism = area of base * height

volume of prism = 48 cm^2 * 20 cm

volume = 960 cm^3
