A jewel case for a DVD.
20 mm 1 centimeter = 10 millimeters 1 millimeter = 0.1 centimeter
1 centimeter = 10 millimetersso20 millimeters = (20 / 10) = 2 centimeters
20 centimeters is equal to 0.2 meters.
20 inc x 16 inc in centimeter is 50.8 cm x 40.64 cm.
20
20 cm = 0.656 feet.
Since about 20 grains of sand lined up is 1cm, then I can use the volume formula (bwh) and subsitute in 20 grains of sand. 20*20*20=8000. There are about 8000 grains of sand in a cubic centimeter.
10 mm per 1 centimeter so 200 divided by 10 = 20.
0.2 m 1 meter = 100 centimeter 1 centimeter = 0.01 meter
If you want to convert that to meters, divide the number by 100.
The perimeter of a rhombus is equal to 4 times the length of one side, so for a rhombus-shaped highway sign with a 20-centimeter side, the perimeter would be 4 x 20 = 80 centimeters.
