One way to find the surface area of a rectangular prism, is to find the area of each side.

Say it has a:

length of 4

Width of 2

Height of 2

multiply height and width = 4x2(for the fact of the opposite side)= 8

next comes length and width= 8x2= 16

finally, do length and height=8x2= 16

so you add them all together, and you get a surface area of 40(inches, centimeters, or whatever the unit of measurment is)

To find the surface area of a rectangular prism, one would multiply the length by its width by its height. So, Surface Area = b x w x h. This equation would probably come up in a Google search, as any similar equations you may need would.

It is not possible. For example, the prism could be tall and thin, or short and thick, and either way have the same surface area.
