The formula of cuboid and cube's edge length and volume A rectangular block of wood is 2.7 meters long, 1.8 meters wide and 5 meters long. It should be cut into small cube blocks of equal size. No surplus is allowed. How many decimeters is the maximum edge length of a small cube?

The formula of cuboid and cube's edge length and volume A rectangular block of wood is 2.7 meters long, 1.8 meters wide and 5 meters long. It should be cut into small cube blocks of equal size. No surplus is allowed. How many decimeters is the maximum edge length of a small cube?


Volume = rectangle * width * height
The volume of a cube is equal to the cubic of its edge length
Do this problem first unified unit, 2.7m = 27dm, 1.8m = 18dm, 1.5m = 15dm
Then, this test is your greatest common factor
The maximum factor of 27, 18 and 15 is 3. Therefore, a: the edge length of a small cube is 3 decimeters
