What is the volume of the following triangular prism?
sergiy2304 [10]

Answer:

<h2>288 ft³</h2>

Step-by-step explanation:

The formula of a volume of a prism:

V=BH

where

<em>B</em><em> - area of a base</em>

<em>H</em><em> - height of a prism</em>

<em />

In the base we have the right treiangle. The formula of an area of a right triangle is:

A=\dfrac{ab}{2}

where

<em>a, b</em><em> - are legs</em>

We have

a=6\ ft,\ b=8\ ft

Substitute:

B=\dfrac{(6)(8)}{2}=\dfrac{48}{2}=24\ ft^2

Calculate the volume.

Substitute

B=24\ ft^2,\ H=12\ ft

V=(24)(12)=288\ ft^3
