Question

Help!! please! i don’t understand

Answer 1

`2 \sqrt[3] {60}~mm`

Explanation:

The volume of a cube is the side cubed, so each edge is the cubic root of the volume.

V = 480 mm³

`s = \sqrt[3] {V}`

`s = \sqrt[3] {480~mm^3}`

`s = \sqrt[3] {2^3 * 2^2 * 3 * 5~mm^3}`

`s = \sqrt[3] {2^3} * \sqrt[3] {2^2 * 3 * 5~mm^3}`

`s = 2 \sqrt[3] {60}~mm`
