Finding the Surface Area of a Cube

To find the surface area of a cube, we need to know the volume of the cube. In this case, the volume of the cube is given as 8 cm³.

The formula for the volume of a cube is:

V = a³

Where V is the volume and a is the length of one side of the cube.

To find the length of one side of the cube, we can take the cube root of the volume:

a = ∛V

Substituting the given volume of 8 cm³ into the formula, we get:

a = ∛8

Calculating the cube root of 8, we find that:

a = 2 cm

Now that we know the length of one side of the cube is 2 cm, we can find the surface area.

The formula for the surface area of a cube is:

A = 6a²

Where A is the surface area and a is the length of one side of the cube.

Substituting the value of a
