Question

Find the cost of lining a lidless rectangular tank 68-in. long, 54-in wide, and 48-in deep,
with zinc, weighing 5.2 lb. per square foot, at $ 1.55 per pound installed.

Answer 1

Answer:

The tank is topless so there is only a bottom

The area of the bottom is 68*54 square inches

there are two sides that are 68*48 square inches and two that are 54*48 square inches

68*54 +2(68*48)+2(54*48)=15984 square inches

Since there are 144 square inches in a square foot, then there are

15984/144 square feet or 106.833 square feet

Now take 106.833 * 5.2 for the weight and divide by 1.55 for the cost
