How to find the surface area of a prism
First, what is a prism? A prism is a rectangular solid with a length, a width, and a height.
To find the surface area you are trying to figure out the total area of the surface of the prism.
The formula for finding the surface area equals
2* (length *width) + 2(length*height) + 2*(height * width) = Surface area of a prism
Find the surface area of a prism with a length of 6 units, a height of3 units and a width of 4 units.
Step 1. Plug in the appropriate units in the formula
2* (6*4) + 2(6*3) + 2( 3*4)
(L*W) ( L*H) (H*W)
Step 2. 2*24 + 2*18 + 2*12
Step 3. 48+36+24 = 108 units squared
Surface area is always squared
