Mathematics: put three cubes with a surface area of 24 square centimeters into a cuboid, the surface area of the cuboid is () square centimeters, and the volume is () process
24 △ 6 = 4 square centimeter (area of one surface)
The surface area of the cuboid is 4 × 6 × 3-4 × 4 = 56 square centimeters
4=2×2
So, the edge length is 2 cm
Volume = 4 × 2 × 3 = 24 CC
