Question

A plastic alphabet cube is 7 cm on each side. What is the surface area of the cube?

Answer 1

Cube's features;

• 6 sides to a cube

• All side lengths are equal, so all areas are the same

Given this information, we must find the area of one side and multiply that area by 6 since there are 6 equal sides of the same area.

Formula for area of square:-

A = a^2

or

A = a · a

Where 'a' represents the length of one side.

Plug in values;

A = a^2

A = 7^2

A = 49 centimetres is the area of one side.

Now we find the areas of all sides (6 sides in total);

49(6)

= 294 is the surface area of the cube.

Answer 2

In a cube, the length and width are the same, so both sides will be 7 cm, yielding an area of 49 square centimeters.
