Question

A triangular prism is 9 feet long. It has a triangular face with a height of 11.3 feet. The volume of the prism is 498.33 cubic feet. What is the base of its triangular face?

Answer 1

9.8 feet

Explanation:

let area of triangular base be A square feet.

volume of prism = A x height(or length in this case)

498.33 = A x 9

A = 498.33 / 9 = 1/2 x 11.3 x base

...

thus, base = 9.8 feet
