how many bricks each measuring 20 cm x 10 cm x 8 cm , will be needed to build a wall 10 m x 8 m x 24.5 m
"explanation : no . of bricks = volume of the wall / volume of 1 brick = ( 1000 x 800 x 24.5 ) / ( 20 x 10 x 8 ) = 12250 answer : a"
divide(multiply(multiply(10, 8), 24.5), divide(divide(multiply(multiply(20, 10), 8), const_100), const_100))
