Cut a cuboid 8 cm long, 5 cm wide and 3 cm high into the largest cube. What is the volume of the cube? (calculation process)

Cut a cuboid 8 cm long, 5 cm wide and 3 cm high into the largest cube. What is the volume of the cube? (calculation process)

The side length of the largest cube is 3 cm, and the volume of this cube is 3 * 3 * 3 = 27 cubic cm

A cuboid block is 20 cm long, 10 cm wide and 8 cm high. After cutting the largest cube block from the block, what is the volume of the remaining part

The edge length of the largest cube block is 8 cm
20 * 10 * 8-8 * 8 * 8 = 1088 CC

Cut a cuboid wood 16 cm long, 8 cm wide and 8 cm high into two cubes
How many square centimeters will the surface area increase? What is the volume of each cube

youmy8015,
The edge length of cube is: 16 △ 2 = 8 (CM)
The surface area will increase: 8 × 8 × 2 = 128 (square centimeter) because everything has two more faces
The cube volume is: 8 × 8 × 8 = 512 (cubic centimeter)
