You could have converted to meters first: 100 cm = 1.00 m; 150 cm = 1.50 m; and 200 cm = 2.00 So, the volume is 1.00 x 1.50 x 2.00 m = 3 cubic meters. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
