Question

the foundation of the house has the following measurements: 60 ft by 40ft by 2ft. if the cement cost 0.03 per pound and weighs 15 lbs/ cu ft, how much will the foundation cost?​

Answer 1

$2160

Explanation:

The volume would be the length width height multiplied together.

Thus, the volume is 60 * 40 * 2 = 4800 cubic feet

Now, let's find the weight.

Since 15 pounds PER cubic feet and we have 4800 cubic feet, we multiply:

15 * 4800 = 72,000 pounds

The weight is 72,000 pounds

The cost is $0.03 per pound, so the cost of 72,000 pounds is:

72,000 * 0.03 = $2160
