A hollow cube is made of paper to have a volume of 512 cubic units. How much paper in square units will be required to make the cube?

Volume of the hollow cube = 512 cubic units.

Volume of a cube: Volume = $$\text{side}^3$$​​

Surface area of a cube (since it’s hollow, only the outer surface area is needed):

Surface Area = $$6 \times (\text{side}^2)$$​​

​$$\text{side}^3 = 512$$​​

​$$\text{side} = \sqrt[3]{512} = 8 \text{ units}$$ 

Now, 

​$$\text{Surface Area} = 6 \times (\text{side}^2) = 6 \times (8^2) = 6 \times 64 = 384 \text{ square units}$$​​

Thus, The paper required to make the hollow cube is 384 square units.
