Question

A rectangular prism has a volume of 90 cubic feet. The prism has a height of 2 feet and a width of 3 feet.

What is the length of the prism?

Answer 1

To find the length of the rectangular prism, we can use the formula for the volume of a rectangular prism:

\[
\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}
\]

We are given the volume, width, and height of the prism:

- Volume = 90 cubic feet
- Width = 3 feet
- Height = 2 feet

Substituting the known values into the volume formula, we have:

\[
90 = \text{Length} \times 3 \times 2
\]

Simplifying the equation:

\[
90 = \text{Length} \times 6
\]

To isolate the length, divide both sides by 6:

\[
\text{Length} = \frac{90}{6} = 15
\]

Thus, the length of the prism is:

\[
\boxed{15} \text{ feet}
\]
