The surface area of a cube is 54 square decimeters. What is the sum of all the edges of the cube?

The base area of the cube is 54 △ 6 = 9 (square decimeter), and because of 3 × 3 = 9, its edge length is 3 decimeters, and the total edge length is 3 × 12 = 36 (decimeter). A: the sum of all edge lengths of the cube is 36 decimeters
