You can put this solution on YOUR website!
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%2F50=20000


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