Question 207042: A cubic box of side 1m is placed on the floor. A second cubic box of side
2/3m is placed on top of the first box so that the center of the second box is directly above the center of the first box. A painter paints all of the surface area of the two boxes that can be reached without moving the boxes. What is the total area of surface that is painted?
(A) 49/9 m^2 (B) 57/9 m^2 (C)61/9 m^2 (D)72/9 m^2 (E) None of these Answer by rfer(16322) (Show Source):
You can put this solution on YOUR website! c) 61/9m^2
large box
each side =1m^2
5 sides =5m^2=45/9m^2
but remember we have to subtract the area of one side of the smaller box
2/3*2/3*5=20/9m^2
45/9+20/9-4/9=61/9m^2
