calculate the number of bricks , each measuring 25 cm * 15 cm * 8 cm required to construct a wall of dimensions 10 m * 4 m * 5 m when 10 % of its volume is occupied by mortar ?
10 * 4 / 100 * 5 * 90 / 100 = 25 / 100 * 15 / 100 * 8 / 100 * x 10 * 20 * 90 = 15 * 2 * x = > x = 6000 answer : c
divide(divide(multiply(multiply(multiply(multiply(10, const_100), multiply(4, const_100)), multiply(5, const_100)), divide(subtract(10, const_1), 10)), multiply(multiply(25, 15), 8)), 10)
