how many bricks , each measuring 5 cm x 11 cm x 6 cm , will be needed to build a wall of 8 m x 6 m x 2 cm ?
"number of bricks = volume of the wall / volume of 1 brick = ( 800 x 600 x 2 ) / ( 5 x 11 x 6 ) = 2909 . answer : option c"
divide(multiply(multiply(multiply(8, const_100), multiply(6, const_100)), 2), multiply(multiply(5, 11), 6))
