find the number of bricks, each measuring 25 cm x 16 cm x 10 cm required to construct a wall 24 m long, 6 m high and 0.4 m thick. the mortar occupies (1/10)th of the volume of the wall

V = 25 * 16 * 10
V = 4,000
0.9 * 4,000 = 3,600 cubic meters
0.25 * 0.16 * 0.1 = 0.004 cubic meters for each brick
3600 / 0.004 = 900,000 bricks
