Given that the length, width and height of the prism are 3ft, 2ft and 4ft respectively. We want to find the surface area of the prism.

Surface Area of a Prism Formula:Surface Area of a Prism Formula: The surface area of a prism with lengthl, widthw, and heigh this given by

Surface area =\(\displaystyle{2}{\left({w}{l}+{l}{h}+{h}{w}\right)}\)

Using the above formula the surface are is

Surface area =\(\displaystyle{2}{\left({2}×{3}+{3}×{4}+{4}×{2}\right)}{52} {f}{t}^{{2}}\)

Thus, the surface area of the prism is \(\displaystyle{52} {f}{t}^{{2}}.\)
