 Problems from 03/18/10 PROBLEM # 1 There is a number that is 5 times the sum of its digits. What is this number?45.
PROBLEM #2 I have a miniature Pyramid of Egypt. It is 4 inches in height. I was invited to display it at an exhibition. I felt it was too small and decided to build a scaledup model of the Pyramid out of material whose density is (1 / 4) times the density of the material used for the miniature. I did a "backoftheenvelope" calculation to check whether the model would be big enough. You may also access this article through our website http://www.lokvani.com/
