Question

Lauren made a large compost bin in her back yard. What is the volume of the compostbin?

Answer 1

1365 ft^3

Explanation:

The compost bin can be thought of as being formed of two boxes.

The volume of the front box is

`(7ft)(21ft)(5ft)=735ft^3`

And the volume of the box at the end is

`(3ft)((3+7)ft)(21ft)=630ft^3`

Hence, the volume of the compost bin is the sum of the volumes above.

`\begin{gathered} V=735ft^3+630ft^3 \\ V=1365ft^3 \end{gathered}`

The volume of the compost bin is 1365ft^3.
