How do you find surface area of a box?

You add the areas of each of the six sides. See these sites for diagrams and more information.

To find the surface area of a box, follow these steps:

1. Identify the dimensions: A box has three dimensions - length (L), width (W), and height (H).

2. Find the areas of each face: A box has six faces, so you need to find the area of each face. The top and bottom faces have the same dimensions, which is the product of the length and width (L x W). The front and back faces also have the same dimensions and can be calculated as the product of the length and height (L x H). Finally, the left and right faces are found by multiplying the width and the height (W x H).

3. Add up the areas: Once you have calculated the area of each face, add them together to find the total surface area of the box. The formula for surface area is:

Surface Area = 2(L x W) + 2(L x H) + 2(W x H)

or

Surface Area = 2lw + 2lh + 2wh

4. Multiply by a conversion factor if necessary: If the dimensions were given in a different unit, ensure that all dimensions are in the same unit before calculating the surface area.

Following these steps will allow you to accurately find the surface area of a box.
