Final answer:
To determine the weight of 3 1/5 cubic feet of water, multiply the weight of one cubic foot (62 1/2 pounds) by 3.2, resulting in 200 pounds.
Step-by-step explanation:
To find out how much 3 1/5 cubic ft of water weighs, if one cubic foot of water weighs 62 1/2 pounds, you simply multiply the weight of one cubic foot by the total cubic feet. So, you would calculate:
62.5 pounds/cubic foot × 3.2 cubic feet = 200 pounds.
This is because 3 1/5 is equal to 3.2 when converted to a decimal. By applying the conversion factors, we obtain an answer in pounds.
