Find the surface area and the sum of the lengths of the edges of a cube whose edge is 11 cm.

Spovcube = 6 * a ^ 2, where a is the length of the edge of the cube, 6 is the number of cube faces, and a ^ 2 is the area of one face of the cube
Since the length of the edge is known to us and it is 11 cm, we get:
Spovkub = 6 * 11 ^ 2
Spovkub = 6 * 11 * 11
Spovkub = 6 * 121
Svcube = 726 (cm ^ 2)

Since the cube has only 12 edges, the sum of the edges will be:
12 * 11 = 132 (cm)

Answer: 726 cm ^ 2, 132 cm
