We have the perimeter of a base P = 20".

We have five congruent rectangles that together form a large rectangle

20" × 6".

The Lateral Area:

L.A. = 20 in · 6 in = 120 in²

Answer:

120 in ^2

Step-by-step explanation:

To find the lateral surface area we find the surface area sides.  It does not include the top and bottom.

The lateral surface area is the perimeter times the height

LSA = P * h

  We know the perimeter = 20 and the height is 6

LSA = 20*6

      = 120  in ^2
