Answer = ft3

Correct Answer

(1) 128

Explanation

To convert the weight of a gallon of water into its volume in cubic feet, follow these steps:

  1. A gallon of water weighs 8 pounds.
  2. The density of water is approximately 62.4 pounds per cubic foot (check the table below).

We can now calculate the volume using the formula:

$\text{Volume (cubic feet)} = \frac{\text{Weight (pounds)}}{\text{Density (pounds per cubic foot)}}$

Substitute the known values

$\text{Volume} = \frac{8 \text{ lb}}{62.4 \text{ lb/ft}^3}  ≈ 0.128 \text{ ft}^3$

So, the volume of a gallon of water is approximately 0.128 ft3
