Question

Solve.

Answer 1

Answer: 11.7 lb

Step-by-step explanation:

You know that the water in a tank weighs 731.25 lb and one cubic foot of water weighs 62.5 lb.

Therefore,  to calculate the the cubic feet of water that the tank holds, you must divide the weight of the water in the tank by the weigth of a one cubic foot of water

Keeping this on mind, you have:

 $x=\frac{731.25lb}{62.5lb}\\x=11.7lb$

Answer 2

Answer:  11.7 cubic feet

Step-by-step explanation:

Since,

$62.5 \text{ lb} = 1\text{ cubic feet}$

$\implies 1 \text{ lb} = \frac{1}{62.5}\text{ cubic feet}$

$\implies 731.25\text{ lb} = \frac{731.25}{62.5}\text{ cubic feet}$

$\implies 731.25\text{ lb} = 11.7 \text{ cubic feet}$

Thus, the tank hold 11.7 cubic foot of water.
