What is the surface area-to-volume ratio of this cube?

Given dimention, sides are 5
SA=6s^2
V=s^3

SA=6(5^2)=6(25)=150
V=5^3=125

SA:V=150:125=30:25=8:5
ratio is 8:5

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
