how many bricks each measuring 25 cm x 11.25 cm x 6 cm , will be needed to build a wall 8 m x 6 m x 22.5 m
"explanation : no . of bricks = volume of the wall / volume of 1 brick = ( 800 x 600 x 22.5 ) / ( 25 x 11.25 x 6 ) = 6400 answer : c"
divide(multiply(multiply(8, 6), 22.5), divide(divide(multiply(multiply(25, 11.25), 6), const_100), const_100))
