Question

Find the volume of the prism.

Answer 1

Choice D.) would be correct

Answer 2

First, let's find the area of the triangle:

$A=\dfrac{1}{2}bh=\dfrac{1}{2}\times3\times4=6$

Now, we multiply this area by the length of the prism, which is 20

$20\times6=120$

All 3 answers have 120. However, since we're calculating volume, it will be represented by $\text{units}^3$. Since no specific unit (such as cm or in) is specified, it will be left at that.

Thus, the answer is answer choice D.
