Solve.What is the weight of a concrete wall that is 25 feet long, 5 feet high, and 8 inches thick? Assume concrete weighs 150 pounds per cubic foot. Round to the nearest pound.
Fill in the blank(s) with the appropriate word(s).
12,500 pounds
V = 25 ft × 5 ft = 125 sq ft = 18,000 sq in
18,000 sq in. × 8 in. = 144,000 cu in.
144,000 cu in. = 12,500 lb
