What is the volume of a rectangular prism?

The volume of a rectangular prism of length l, width w and height h is given by:

[tex]V = lwh[/tex]

In this problem, the wooden mold is composed by two rectangular prisms:

  • The first has dimensions of 25 in, 10 in and 12 in.
  • The second has dimensions of 20 in, 12 in and 12 in.

Hence the volume in cubic inches is given by:

[tex]V = 25(10)(12) + 20(12)(12) = 5880[/tex]

Rounding, it is closest to 6000 in³, hence option C is correct.
