Lets split the box in pieces and then add:
top = 20*15 = 300
sidesA = 2*20*9 = 360, is multiplied by 2 cause there are 2 sides like this
sidesB = 2*9*15 = 270, is multiplied by 2 cause there are 2 sides like this
so in total we have:
total = 300 + 360 + 270 = 930 cm^2
if we express this quantity in mm^2 we have:
<span>1cm² = 100 mm²</span>total = 930*100 = 93000 mm^2
so if the tiles are 5 mm^2 we need:
total tiles = <span>93000/5 = 18600
we need 18600 tiles of 5 mm^2</span>
Meter, liter, and gram are all basic units of measure in the metric system.
The U.S. customary system and the metric system are the two major systems of measurement. The system of measurement that uses the meter, liter, and gram as the base units of length (distance), capacity (volume), and weight (mass) is referred as Metric system.
Most of the countries use the metric system but in the United States, the US Customary system is used where the things are measured in feet, inches, and pounds. Meter, liter, and gram are all basic units of measure in the metric system.
