Question

Julio bought a fish tank shaped like a rectangular prism. The inside of the tank measures 24 inches in length, 10 inches in width, and 12 inches in height. The tank is filled with water to a height of 8 inches. How many more cubic inches of water are needed to fill the tank to the top? Use paper to show your work.

Answer 1

`Volume = 960in^3`

Explanation:

Given

Empty Tank

`Length = 24in; Width=10in; Height = 12in`

When filled with water, the height is:

`Height = 8in`

Required

Determine how many more cubic inches needed

First, we calculate the difference between the height of the tank and the height of the water.

`H = 12in - 8in`

`H = 4in`

The volume of water to full the tank is then calculated as:

`Volume = Length * Width * H`

`Volume = 24in * 10in * 4in`

`Volume = 960in^3`
