To find the volume of a rectangular prism, you use the formula:
\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]
Since you provided a few volume options (90, 180, 900) and a unit choice, let's clarify the correct unit for volume. The appropriate unit for volume is cubic feet.
So, if you were to choose one of the volume options and the correct unit, a complete answer would look like this:
- Volume: choose one of the values (90, 180, 900)
- Unit: cubic feet
For example, if you select 180, your complete answer would be:
180 cubic feet.
Make your selection based on the information you have for the dimensions of the prism.
