Question 863452
SA = 6s^2



600 = 6s^2



600/6 = s^2



100 = s^2



s^2 = 100



s = sqrt(100)



s = 10



So the old cube has side lengths of 10 inches. Now reduce each edge by half to get 10*(1/2) = 5. The new cube has side lengths of 5 inches.



Now compute the surface area of the smaller cube.



SA = 6s^2



SA = 6*5^2



SA = 6*25



SA = 150



The new surface area is <font size=4 color="red">150 square inches</font>. Notice how this is 1/4 of the original surface area and how 1/4 = (1/2)^2
