The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube with a surface area of 180 square meters than a cube with the surface area of 120 square meters?
StartRoot 30 EndRoot minus 4 StartRoot 5 EndRoot meters m
StartRoot 30 EndRoot minus 2 StartRoot 5 EndRoot meters m
StartRoot 10 EndRoot meters m
2 StartRoot 15 EndRoot meters m

s = sqrt(SA/6). For SA = 180: s1 = sqrt(180/6) = sqrt(30). For SA = 120: s2 = sqrt(120/6) = sqrt(20) = 2√5. Difference = √30 − 2√5.

Answer: √30 − 2√5 meters.
