Question

The surface area of a rectangular prism is the sum of:

Answer 1

Answer:

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

Step-by-step explanation:

We are given that surface area of rectangular prism=$2(lw+lh+wh)$

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)
