Calculation of Cube Volume and Surface Area

To find the volume and surface area of a cube with an edge length of 3 cm, we can use the following formulas:

- Volume of a cube: V = a^3, where a is the length of one side of the cube. - Surface area of a cube: S = 6a^2, where a is the length of one side of the cube.

Substituting the given value of a = 3 cm into the formulas, we can calculate the volume and surface area of the cube.

Volume of the Cube

The volume of the cube is given by the formula V = a^3. Substituting a = 3 cm, we get:

V = 3^3 = 27 cubic centimeters.

Therefore, the volume of the cube is 27 cubic centimeters.

Surface Area of the Cube

The surface area of the cube is given by the formula S = 6a^2. Substituting a = 3 cm, we get:

S = 6(3^2) = 6(9) = 54 square centimeters.

Therefore, the surface area of the cube is 54 square centimeters.

In summary, the volume of the cube is 27 cubic centimeters and the surface area of the cube is 54 square centimeters.
