Question

What is the volume in cubic feet of the prism, rounded to the nearest cubic foot? Do not use units or commas in your answer.

Answer 1

35.1

Explanation:

There's a formula that i've linked as an image

Basically, substitute all 3 sides and the length into that formula, chuck it into the calculator and viola.

Or... we can use pythagoras' theorem and get the height of the triangle Height =
`3^(2)` -
`1.5^(2)` = 2.6

Area of triangle = (3 * 2.6) / 2 = 3.9

Volume = 3.9 * 9

Volume of prism = 35.1
