how many bricks each measuring 20 cm x 13.25 cm x 8 cm , will be needed to build a wall 7 m x 8 m x 15.5 m
"explanation : no . of bricks = volume of the wall / volume of 1 brick = ( 700 x 800 x 15.5 ) / ( 20 x 13.25 x 8 ) = 4094 answer : c"
divide(multiply(multiply(7, 8), 15.5), divide(divide(multiply(multiply(20, 13.25), 8), const_100), const_100))
