Answer:

88 cm²

Explanation:

You want the surface area of the shape in the given figure.

Area

The total surface area will be double the number of colored squares shown.

purple squares = 1×4 +5×2 = 14

blue squares = 1×3 +5×3 = 18

orange squares = 2×3 +2×3 = 12

Total surface area

The total area is then ...

SA = 2(14 +18 +12) = 88 . . . . square centimeters

The surface area is 88 cm².

__

Additional comment

The area is double the number of colored squares because the surfaces you can't see have the same area as the surfaces you can see.
