area = 144 square units perimeter = 48 units

A centimetre is a unit of length. A square centimetre is a unit of area. The two units are therefore incompatible.

Then its area will only be a quater of once it was.

cm stands for centimeters. square centimeters means that you have two measurements of cenitmeters... usually in a geometric shape. When you need to find the area (the area is the space inside the object) your units are square centimeters since you have to multiply centimeters by centimeters.

That refers to units of area, such as square meters, square centimeters, etc.

Multiply the two dimensions to get the area. The calculation will give you 10.8 square centimeters.

Do you mean the surface area of the box? If so... What you do is break the surface area into 6 rectangles: Two rectangles have sides of length 6.3 and 12.6 inches. Two rectangles have sides of length 6.3 and 4.2 inches. Two rectangles have sides of length 12.6 and 4.2 inches. Find the area of each of the six rectangles (using the standard formula for the area of a rectangle, A = W x H), and add up all six. The sum of the areas of the six rectangles will be the surface area of the box. Since the lengths of the sides are in inches, the area will already be in square inches, and therefore you don't have to "turn it into square inches".

Rectangles have two dimensions: length and width. Multiply them together and you will get the area in square units.
