Cut a cube with a surface area of 1.8 square meters into three cuboids of the same size (regardless of loss). What is the surface area of each cuboid?

Cut a cube with a surface area of 1.8 square meters into three cuboids of the same size (regardless of loss). What is the surface area of each cuboid?

After cutting, there are 6 more sections [2 more faces at a time]
The surface area is more: 1.8 × 6 = 10.8 square meters

A cuboid is 4 meters long and becomes a cube. Its surface area is reduced by 120 square meters

Let the length, width and height of the rectangle be a, a, a + 4, the area of the 4 meters intercepted be 2A * a + 4 * 4 * a = 120, and then calculate a, and the rectangle face is 120 + A * a

Cut a cube with edge length of 6 cm from a cuboid. The surface area of the remaining cuboid is 120 square cm. What is the volume of the original cuboid

Side area of the remaining cuboid = 120-6 × 6 × 2 = 48 (square centimeter)
The height of the remaining cuboid = 48 △ 4 △ 6 = 2 (CM)
The volume of the original cuboid = 6 × 6 × (6 + 2) = 288 (cubic centimeter)
