The length of all edges of the cube is 51.6 cm. Calculate the total surface area of the cube.

The cube has 12 edges.

Since the length of all the edges of the cube is 51.6 cm, the length of one of its edges is:

a = 51.6 / 12 = 4.3 (cm).

Let’s calculate the surface area of the cube:

S = 6 * a ^ 2 = 6 * 4.3 ^ 2 = 110.94 (cm²).

Let’s round the answer to tenths:

110.94 cm² ≈ 110.9 cm².

Answer: 110.9 cm².
