Answer:

Surface area of prism=[tex]2(l+w)h+2(lw)[/tex]

Step-by-step explanation:

We are given that surface area of rectangular prism=[tex]2(lw+lh+wh)[/tex]

We have to write an expression that represents the surface area of prism.

Base of prism is made from length and width

Perimeter of base =2(l+w)

Area of base=lw=Area of top

Surface area of prism=Perimeter of base multiply by height+2 area of base

Because area of base and area of top are equal.

Surface area of prism=Ph+2B=2(l+w)h+2(lw)
