The height of a right rectangular prism is 3 units greater than the length of the base. the edge length of the square base is x units.

which expression represents the volume of the prism, in cubic units?

x3 + 9
x3 + 3x2
x3 + 3x + 3
x3 + 6x2 + 9x

For this case, the first thing you should keep in mind is that the volume of the rectangular prism is given by:

Where,

w: width of the prism

l: prism length

h: prism height

Substituting values we have:

Then, rewriting we have:

An expression that represents the volume of the prism, in cubic units is:
