When using a net what is the correct formula to find surface area of a prism with length, width, and height
The correct formula to find the surface area of a prism using its net (unwrapped form) is:
Surface Area = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
This formula accounts for the top and bottom faces, the front and back faces, and the left and right faces of the prism.
