Cut a cube wood block with an edge length of 8 decimeters into the largest cylinder. How many cubic decimeters is the volume of this cylinder?

Cut a cube wood block with an edge length of 8 decimeters into the largest cylinder. How many cubic decimeters is the volume of this cylinder?

The cube with an edge length of 8 decimeters has a volume of 8 * 8 * 8 = 512 cubic decimeters
The maximum diameter of the bottom surface of the cylinder is 8 decimeters
Volume of cylinder = 3.14 * 4 ^ 2 * 8 = 452.16 cubic decimeter
The volume of this cylinder is 452.16 cubic decimeters

How many cubic decimeters is the volume of the largest cylinder?

The maximum circle has a radius of 2 decimeters and a height of 4 decimeters,
Volume = 3.14 * 2 * 2 * 4 = 50.24 cubic decimeter
