Cut a cuboid 20 cm long, 16 cm wide and 12 cm high into the largest cube. How many cuboids are left
The side length of cube can only be the shortest side of cuboid, that is 12 cm
20×16×12 - 12×12×12
＝3840 - 1728
= 2112 (cm3)
2112 cubic centimeters left
The cuboid is 6 decimeters long, 2 decimeters wide and 4 decimeters high. Cut the cuboid into the largest cube. What is the volume of the cube?
How many cubes can this cuboid cut?
The side length of the cube is 2 decimeters
Volume 2x2x2 = 8 decimeters
It can be cut into 6x2x4 △ 8 = 6 pieces
If you don't understand this question, you can ask,
Cut a cuboid 12 cm long, 9 cm wide and 8 cm high into the largest cube. The volume of the needle spinning body is
The original cuboid, 12 in length, 9 in width and 8 in height, is cut into a cube. The maximum side length can only be 8. The volume of the cube is 8x8x8 = 8 ^ 3 = (2 ^ 3) ^ 3 = 2 ^ 9 = 512
