Question

Please someone help me answer this.

Answer 1

Volume: 72 cubic in.

Equation for height:
`{{72\over{8\cdot{2} {1\over4}}}={h}`

Explanation:

The volume is the brick is 5.76 over 0.08, because it is 0.08 lb per cubic inch.

Now, we divide to get 72 cubic inches. This is the volume of the brick.

To find the height, we can use what we found as the volume and set up an equation:
`{{72\over{8\cdot{2} {1\over4}}}={h}`. This means h is 72 over 18, or h = 4.
