Sagot :

Answer:

88 square cm

Step-by-step explanation:

The surface area of the composite 3-D shape given is made up of 8 parts. Those parts are 1x3, 5x3, 6x3 (on the top and bottom), 2x3, 2x3, 4x3 (right and left) and the front and back are made up of two identical shapes which each are made up of a 2x6 and a 1x2. Add up all of these areas to get 3 + 15 + 18 + 6 + 6 + 12 + 12 + 2 + 12 + 2 which is equal to 88.

Hope this helps :)
