A cube is a regular polyhedron, each face of which is represented by a square, and the edges are equal.
The surface area of such a figure is determined by the formula:
S = 6a².
Provided that this value is 10.14 cm², we express the side. To find the second factor, divide the product by the first:
a² = S: 6 = 10.14: 6 = 1.69, and = √1.69 = 1.3 cm – the edge or side of the cube.
