Find the surface area of a cube whose edge length is a) 10cm b) 5cm c) 1m d) 13dm

A cube is a regular polyhedron, each face of which is a square, and all its edges are equal.

Its surface area is calculated by the formula:

S = 6a². Let us determine its value, provided that the length of the edge is:
a) 10 cm:

S = 6 * 10² = 6 * 100 = 600 cm².

b) 5 cm:

S = 6 * 5² = 6 * 25 = 150 cm².

c) 1 m:

S = 6 * 1² = 6 cm².

d) 13 dm:

6 * 13² = 6 * 169 = 1014 dm².
