how many bricks , each measuring 25 cm x 11 cm x 6 cm , will be needed to build a wall of 2 m x 3 m x 2 cm ?
"number of bricks = volume of the wall / volume of 1 brick = ( 200 x 300 x 2 ) / ( 25 x 11 x 6 ) = 72.7 = 73 . answer : option c"
divide(multiply(multiply(multiply(2, const_100), multiply(3, const_100)), 2), multiply(multiply(25, 11), 6))
