Question

a cube has a volume of 216 cm³ if the cube is completely covered with wrapping paper what is the minimum amount of paper needed to cover all 6 surfaces

Answer 1

we have given that volume of cube is 216 cm^3.

we know that cube will have 6 surfaces.

before that we need to know what is edge of a cube from volume.

`volume=a^3=216`.

a
`a=6cm.`.

now we know that edge is 6cm .

we need to find surface area of cube to cover paper of minimum area.

`surface area=6a^2=6*(6)^2=216 cm^2`
