Gabriel unfolded a cube to form the net below.

rewona [7]

1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.

36/4 = 9 cm per edge.

2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.

81 square cm x 6 = 486 square cm

486 square cm is the surface area.
