The pyramids have always fascinated kristina, so she wants to build two model pyramids to put on her mantel. she wants her model of khufu's pyramid to have a volume of 73.5 cubic inches and a height of 4.5 inches. what would the side length of the base of the pyramid be? is this number rational or irrational? why?

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.
