Answer:
[tex]V=120\ units^3[/tex]
Step-by-step explanation:
we know that
The volume of a prism is equal to
[tex]V=BL[/tex]
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
[tex]B=\frac{1}{2}(3)(4)=6\ units^2[/tex] ---> area of a triangle
we have
[tex]L=20\ units[/tex]
substitute in the formula of volume
[tex]V=6(20)=120\ units^3[/tex]
Note The problem does not specify whether the measurements are in centimeters or in units, so I assume they are in units.
