I need help on #9. The help would be grateful appreciated.
1 answer:
Original Figure: Length = 15 Width = 5 Height = 10 Volume = Length*Width*Height Volume = 15*5*10 Volume = 750 New Figure Length = 3 Width = 1 Height = 2 Each dimension has been divided by 5 (eg: 15/5 = 3) Volume = Length*Width*Height Volume = 3*1*2 Volume = 6 The old volume was 750 and it changes to 6 Notice how 750/6 = 125 Which can be rearranged to 750/125 = 6 Answer: if you divide the old volume by 125, then you get the new volume Note: the new volume is 125 times smaller than the old volume Put another way, the old volume is 125 times larger compared to the new volume The fact that 125 = 5^3 is not a coincidence. If you divide each dimension by some number k, then you divide the volume by k^3
