Ten unit cubes are glued together as shown. How many square units are in the surface area of the resulting solid?
+2440 Solution:
Subtract covered surface area from total surface area
Total Surface Area = 10*[(6)*(12)] = 60 units2
Covered Surface Area = 14 units2 (vertical) + 12 units2 (horizontal) = 26 units2
Surface Area of resulting solid = 60 units2 - 26 units2 = 34 units2
Kudos to Hectictar for noticing my error.
