To calculate the surface area of a box, find the area of each face, and add all answers together. For example, the surface area of a square whose faces are all 2" by 2" can be calculated with the following equation:
2x2x6
2x2 equals 4. Since a square's sides are all the same length, we can simply multiply 4 by the number of faces on a square(6), instead of 4+4+4+4+4+4. THIS IS ONLY TRUE FOR SQUARES! I REPEAT, THIS IS ONLY TRUE FOR SQUARES!!!! For all other shapes, the sides are NOT all the same length. So THIS IS ONLY TRUE FOR SQUARES!
No. If you want the area of a single surface of a box, simply multiply the height by the width of the surface of interest.
multiply the height by the width
You measure the sides, and multiply the top and side.
If it's just the front surface of a box then it's simply a 2D shape, the area can be calculated by multiplying the length by the width. Answer will be in units squared.
The surface area of each side of the box ( there should be six sides unless it doesn't have a top ) added together will give you the total surface area. The surface area of one side is calculated by multiplying the length and the width. The answer will be in square inches or square centimeters depending on what unit of measure you use.
to calculate the area of the front surface of a box you should
multiply the length by the height

Measure the height and multiply it by the width.

You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
surface area divided by volume
height x length
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
