A load of 3 inches of water is equivalent to how many pounds?

• A. 7
• B. 14
• C. 21
• D. 28

Answer: (C)

To determine the weight of a load of water, it's essential to know that water weighs approximately 8.34 pounds per gallon. A 3-inch measurement usually refers to a depth or height of water, not a volume directly. However, if we assume this is related to a specific area and convert it into a volume, we can calculate its weight. For example, if you were considering a small area, such as 1 square foot, and had a height of 3 inches of water, the volume would be: 1 square foot = 144 cubic inches To convert 3 inches to feet: 3 inches = 0.25 feet (since there are 12 inches in a foot). Now, the volume of 1 square foot of 3 inches of water would be: 1 square foot x 0.25 feet = 0.25 cubic feet. There are 7.48 gallons in a cubic foot, so: 0.25 cubic feet x 7.48 gallons/cubic foot = 1.87 gallons. Now multiplying by the weight of water gives: 1.87 gallons x 8.34 pounds/gallon ≈ 15.58 pounds for the 3-inch load over a 1

To convert 3 inches to feet:

3 inches = 0.25 feet (since there are 12 inches in a foot).

Now, the volume of 1 square foot of 3 inches of water would be:

1 square foot x 0.25 feet = 0.25 cubic feet.

There are 7.48 gallons in a cubic foot, so:

0.25 cubic feet x 7.48 gallons/cubic foot = 1.87 gallons.
