In order to find the sum of all edges and the sum of the areas of all faces of a cube with a volume of 125 m³, it is necessary, first of all, to find each edge.
a³ = 125, hence the edge is 5 m.
L = 12а = 12 * 5 = 60 m – the length of all the edges of the cube.
S = 6а² = 6 * 5² = 6 * 25 = 150 m² – the surface area of the cube.
