Answer:
1.2 cubic feet the water weighs 75 lb.
Step-by-step 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:
[tex]75\div 62\frac{1}{2}[/tex]
[tex]=75\div \frac{125}{2}[/tex]
[tex]=75\div 62.5[/tex]
[tex]=1.2[/tex]
Therefore, 1.2 cubic feet the water weighs 75 lb.
