Question

Find the volume of the tra ezoidal prism in the figure.

A. 72 m3
B. 252 m3
C. 432 m3
D. 216 m3

Answer 1

To solve this problem you must apply the proccedure shown below:

1. You can use the following formula for calculate the volume:

$V=(\frac{a+b}{2})(h)(l)$

Where:

$a=6m\\b=12m\\h=8m\\l=3m$

2. Now, you must substitute the values above into the formula:

$V=(\frac{a+b}{2})(h)(l)\\V=(\frac{6m+12m}{2})(8m)(3m)\\V=216m^{3}$

Therefore, the answer is the last option: D. 216 m³.
