100
(1 metre) squared = (1000 mm) squared = 1000000 mm squared.
1 cm squared is 10mm by 10mm so 1cm squared equals 100mm squared
1 mile = 1.609344 km
1 kilometer = 1,000 meters
1 sq km = 1,000,000,000,000 sq mm
1 cm = 10 mm 1 cm2 = 10 mm * 10 mm = 100 mm2 520 cm2 = 520 * 100 = 52,000 mm2
This is not a valid conversion. Square mm is a measure of area. Cubic mm is a measure of volume.
1 kilometer is 100,000 centimeters.
There are 1000 meters in one kilometer
Since there are 10 mm in 1 cm, one must multiply by 10^2 = 100. So the answer is 100,000 mm squared.
400 mm x 400 mm = 0.4 m * 0.4 m = 0.16 sq metres. So 1 metre squared contains 1/0.16 = 6.25400 mm x 400 mm = 0.4 m * 0.4 m = 0.16 sq metres. So 1 metre squared contains 1/0.16 = 6.25400 mm x 400 mm = 0.4 m * 0.4 m = 0.16 sq metres. So 1 metre squared contains 1/0.16 = 6.25400 mm x 400 mm = 0.4 m * 0.4 m = 0.16 sq metres. So 1 metre squared contains 1/0.16 = 6.25
