Want this question answered?
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
LxWx2
Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...
2lw + 2lh + 2wh
its not i dont no why
I am not sure that a rectangular prism is in any position to care!
The formula will depend on what it is that you are trying to find: the volume or the surface area.
Surface area = 2LW + 2(L+W)H
Formula: S = 2B + L
A= 2(wh+lw+lh) where w = width h = height and l = length When trying to find the surface area of something, it is important to try to remember the specific formula. The formula for the surface area of a rectangular prism is A=2(wl+hl+hw).
The formula for finding the surface area of a rectangular prism is 2(wh + lw + lh), where w is width, h is height, and l is length. 3.14 is the value for pi, which is only used for circular objects, like circles, cylinders, and spheres. It has nothing to do with rectangular prisms. Click on the related link below for an illustration of the formula for the surface area of a rectangular prism.
Depends whether you want the formula for surface area, volume, perimeter, size of sphere it would fit into etc... Please clarify next time.
