Question

Find the volume of the triangular prism described below.

The base is a 45degrees​-45degrees​-90degrees triangle with a leg of 8 in. The height is 3.8 in.

Answer 1

The volume of the prism 121.6 cube in.

Explanation:

Given,

The base is right angle triangle whose two sides are equal.

So,

Base (b) = 8 in

Another side of right angle triangle (l) = 8 in

Height (h) of the prism = 3.8 in

To find the volume of the prism.

Formula:

V =
`(1)/(2)`bhl

Now,

V =
`(1)/(2)`×8×8×3.8 cube in

= 121.6 cube in.
