Best ResponseYou've already chosen the best response.3A cube itself has 6 sides, each with surface area of 1 (L x W which are each 1) So each cube has an area of 6 in^2. 8 cubes, so 48 in^2 In the megacube, each cube only shows 3 of its sides. Therefore, each cube only has 3 in^2 represented. 8 cubes, 3x8 = 24. 48  24 = 24 in^2

Best ResponseYou've already chosen the best response.0Surface area of large cube = 6*2^2 = 24 square inches Surface area of small cube = 6*1^2 = 6 square inches Sum of small cubes surface area = 6*8 = 48 square inches  So the difference is 48  24 = 24 square inches So the answer is A
