Question

Find the volume of the prism.

Answer 1

`V=120\ units^3`

Explanation:

we know that

The volume of a prism is equal to

`V=BL`

where

B is the area of the base of the prism (triangular base in this problem)

L is the length of the prism (perpendicular distance between the top and the bottom)

Find the area of the triangular base B

`B=(1)/(2)(3)(4)=6\ units^2` ---> area of a triangle

we have

`L=20\ units`

substitute in the formula of volume

`V=6(20)=120\ units^3`

Note The problem does not specify whether the measurements are in centimeters or in units, so I assume they are in units.
