gabriel unfolded a cube to form the net below. part a: what is the length, in centimeters, of each edge of the cube? part b: what is the total surface area, in square centimeters, of the cube?

For part A, there are 4 equal lengths put together and the sum of them is 36. So dividing 36/4 gives us 9.

So the length of each edge is 9 cm!

For part B, finding surface area means the total area of the cube on its six faces.

So for one face of the cube, the area is

9 × 9 = 81 cm^2

There are 6 faces so we multiply 81 by 6 and get 486 cm^2.

Hope this helps!
