how many bricks , each measuring 25 cm x 11 cm x 6 cm , will be needed to build a wall of 8 m x 1 m x 5 cm ?
"number of bricks = volume of the wall / volume of 1 brick = ( 800 x 100 x 5 ) / ( 25 x 11 x 6 ) = 242 . answer : option c"
divide(multiply(multiply(multiply(8, const_100), multiply(1, const_100)), 5), multiply(multiply(25, 11), 6))
