Final answer:
To determine the weight of 1 cubic foot of sand in pounds, we need to use conversion factors. By applying the provided conversion factor, 12 in³ = 62.4 lb/ft³, and converting cubic feet to cubic inches, we can find that the weight of 1 cubic foot of sand is 9072 pounds.
Step-by-step explanation:
To determine the weight of 1 cubic foot of sand in pounds, we need to use the conversion factor provided: 12 in³ = 62.4 lb/ft³.
First, convert the cubic foot to cubic inches by multiplying 1 ft³ by (12 in/1 ft)³. This gives us 1728 cubic inches.
Next, use the conversion factor to find the weight in pounds: 1728 in³ * (62.4 lb/12 in³) = 9072 lb. Therefore, the weight of 1 cubic foot of sand is 9072 pounds.
