How many square meters of cardboard should be used to make a cube carton with an edge length of 6 decimeters?
What this problem seeks is the surface area of cube
One edge is 6 decimeters long
So the area of a surface = 6 & # 178; = 36 square decimeters
Cube surface area = 6 × 36 = 216 square decimeters = 2.16 square meters
answer
At least 2.16 square meters of cardboard is required
