No, they are both the same.
500mm 1cm = 100mm
50 millimeters=5 centimeters
500mm = 50cm
500mm is 50cm (divide mm by 10).
If the tank is a cube, and each edge is 500mm long, then the volume of the tank is50cm x 50cm x 50cm = 125,000 cm3 = 125 litres.
270mm x 500mm x 500mm = 67,500,000 mm3In terms of liquids, this equates to about 17.8 US gallons or 14.8 UK gallons
500mm=50cm and 502cm = 2500cm.
5cm*5cm*5cm = 125 cubic cm.
100 millimeters is equal to one decimeter so 500mm is equal to 5 decimeters.
The volume of a cube of 5cm is: 125 cm3
5cm to the 3rd power = 5cm x 5cm x 5cm = 125cm3 (or 125 cubic centimeters)
