After four cubes of the same size are glued into a cuboid, the surface area is reduced by 54 square centimeters, and the surface area and volume of the cuboid are calculated

After four cubes of the same size are glued into a cuboid, the surface area is reduced by 54 square centimeters, and the surface area and volume of the cuboid are calculated

Volume 108, surface product will be calculated later
After gluing into a cuboid, there are three bonding surfaces, so the surface area is actually less than the area of the six surfaces of the original cube, so the area of each surface is 9, and the side length is 3. Then it's better to calculate
