Question

What is the surface area, in square centimeters, of a cube with each edge length of 5 cm?

Answer 1

The surface area of a cube is just the area of all six sides of the cube. Therefore, if we let s = the cube's side,

The surface area would be `6 * s^2` because the area of one face is `s^2` and there are six faces

Given this, we know from the problem that `s = 5`

We can just plug in for s.

SA = `6 * 5^2`

SA = `6 * 25`

SA = `150`
