Question

Building bricks are closely stocked in a pile 7ft. high, 36ft. long and 12ft. wide. If the bricks are 2 in. by 4 in. by 9 in. how many bricks are in the pile?

Answer 1

We know 1 foot = 12 in.
So, volume of pile = 7*36*12 = 3,024 feet^3
converting this to inches we have,
3,024*1728 = 5,225,472 in^3
now , volume of a brick = 2*4*9 = 72 in^3
No. of bricks = 5,225,472 / 72
$5225472 \div 72 = 72576$
72,576 bricks is the answer
