A construction company makes cement stairs from a wooden mold. The construction company must calculate the volume of the mold to

Dahasolnce [82]

Considering the volume of a rectangular prism, it is found that the volume of the wooden mold is given by:

C. 6,000 in³

<h3>What is the volume of a rectangular prism?</h3>

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

$V = lwh$

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:

$V = 25(10)(12) + 20(12)(12) = 5880$

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