Do you remember the formulas for volume and surface area?
Volume: 1 000 000 cm^3
Surface Area: 60 000cm^2
Before calculating the volume and the surface area of the cube, we should find its side length.
We are given that the sum of side lengths of the cube is 1200cm. Since the cube has 12 side, to get the side length s, we should divide the sum by 12. 12s = 1200cm ⇔ s = 100cm
s= 100
