how many bricks , each measuring 25 cm x 11.25 cm x 6 cm , will be needed to build a wall of 4 m x 2 m x 25 cm ?
"number of bricks = volume of the wall / volume of 1 brick = ( 400 x 200 x 25 ) / ( 25 x 11.25 x 6 ) = 1185 . answer : option c"
divide(multiply(multiply(multiply(4, const_100), multiply(2, const_100)), 25), multiply(multiply(25, 11.25), 6))
