What is the volume of the prism below?

a. 648 units^3
b. 112 units^3
c. 324 units^3
d. 226 units^3

For this case we have that the volume of the rectangular prism is given by:

Where:

It is the area of the base

h: It's the height

We have that the base is a triangle, so, the area of the base is the area of the triangle:

The height of the prism is 18 units.

So, the volume is:

Option C

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
