Question

What is the length of a right
rectangular prism with a
volume of 90, width of 3, and
height of 5?

Answer 1

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

\[
\text{Volume} = \text{length} \times \text{width} \times \text{height}
\]

In this case, you know the volume is 90, the width is 3, and the height is 5. Substituting these values into the formula gives you:

\[
90 = \text{length} \times 3 \times 5
\]

Now, calculate \(3 \times 5\):

\[
3 \times 5 = 15
\]

So the equation now looks like this:

\[
90 = \text{length} \times 15
\]

To find the length, divide both sides by 15:

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

Thus, the length of the right rectangular prism is \(6\) units.
