It doesn't matter what the unit of measurement is, or what size the cube is. If the length of the side of the cube is 'S' units, then the volume is S3 and the surface area is 6S2. The ratio of volume to surface area is (S3/6S2) = S/6 units. For this one, the ratio is 1/6 cm.
Because the ratio would;t be correct. Look at this example. What is the ratio of 1cm to 1 metre? If you went by these measurements you would get 1:1 which means 1cm is the same as 1 metre., which is false. The correct answer means comparing 1cm with 100cm (or 1 metre) which is 1:100. So it's really important with ratios that the units are the same.

1cm = 10mm. So 14mm > 1cm.
1cm
The ratio is: 7cm to 1cm
Island need only be 500meters by 500meters.
1m = 100cm. So, 200m = 200x100cm = 20,000cm. 1cm in the map representing 200m on the ground will be 1:20,000 in ratio.
10mm equalls 1cm and 2m equalls 200cm. The ratio is 1:200.

500 meters is 0.311 miles.
(50 km) x (1,000 m/km) x (100 cm/m) = 5,000,000So [ 1cm=50km ] is a scale of 1 to 5 million.

The scale ratio of 1cm to 10m can be calculated by converting both measurements to the same unit. Converting 10m to cm gives us 1000cm. Therefore, the scale ratio is 1:1000, meaning for every 1cm on the map, it represents 1000cm or 10m in real life.
