To find the surface area of a rectangle prism, you need to add the areas of all six sides.
1. Find the area of the top and bottom faces by multiplying the length and width of the prism.
2. Find the area of the front and back faces by multiplying the height and width of the prism.
3. Find the area of the side faces by multiplying the height and length of the prism.
4. Add all six areas together to get the total surface area.
Alternatively, you can use the formula:
Surface Area = 2lw + 2lh + 2wh
(l = length, w = width, h = height)
This will give you the surface area of the rectangle prism.
To check your answer, make sure that all sides are included in your calculations and that your calculations are accurate.
