Question 168702
1 cubic meter = 100 cm * 100 cm * 100 cm = 1,000,000 cubic cm



Volume of 1 brick: 2 cm * 5 cm * 5 cm = 50 cubic cm



Now simply divide 1,000,000 cubic cm (the total volume) by 50 cubic cm (the volume of one brick) to get


{{{1000000/50=20000}}}



So you need 20,000 bricks to get a cubic meter
