Question

Help me out please?!

Answer 1

The volume of any straight prism is the area of the shape base multiplied by the length. In this case, our shape is a triangle and the area of a triangle is $\frac{1}{2}*b*h$ where b is the base and h is the height. In this case, the base is 16 and the height is 8.

$A = \frac{1}{2}*16*8$
$A = \frac{1}{2}*128$
$A = 64$

So, now we know the area of the shape is 64. We need only multiply this by the length of the prism, in this case 22. 

$64 * 22 = 1408 cm^3$

Therefore, the final answer is 1408 $cm^3$.
