Question

The weight of water is 62 1/2 lb per cubic foot. Water that weighs 75 lb will fill how many cubic feet?

Answer 1

1.2 cubic feet the water weighs 75 lb.

Explanation:

It would be density of water 62 1/2 per cubic foot.

Given:

The density of water is 62 1/2 lb per cubic foot.

Now, to find cubic feet of water that weighs 75 lb.

We use unitary method to solve:

If 1 cubic foot the density is 62 1/2 lb.

So, to get the cubic feet of water we divide the weight of water by density:

`75/ 62(1)/(2)`

`=75/ (125)/(2)`

`=75/ 62.5`

`=1.2`

Therefore, 1.2 cubic feet the water weighs 75 lb.
