How many square centimeters is the area of one face of a cube with an edge equal to 3 cm?

How many square centimeters is the area of one face of a cube with an edge equal to 3 cm? What is the sum of the areas of all the faces? How many cubic centimeters is the volume of this cube?

Find the area of one face of the cube. To do this, we raise to the second degree the edge of the cube, equal to 3 cm.

Sg = (3 cm) ² = 9 cm².

A cube has 6 faces, to find out the surface area of the cube, multiply the area of one face of the cube by 6.

S = 9 cm² * 6 = 54 cm².

Let’s find the volume of the cube. Let’s raise the edge of the cube to the third degree.

V = (9 cm) ³ = 27 m³.

Answer: the face area is 9 cm², the surface area is 54 cm², the volume of the cube is 27 m³.
