Question

Determine the volume of the rectangular prism.
​

Answer 1

50 ft³

Explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2
`(1)/(2)` and the height is 2
`(1)/(2)`

8 × 2
`(1)/(2)` × 2
`(1)/(2)`

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2
`(1)/(2)` = 20

20 × 2
`(1)/(2)` = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

50 ft³ is our final answer
