Question:No I don't know what a slide rule is.

Answers:There are 2.54 centimeters to the inch.............if you don't have a calculator, use the calculator function on YOUR COMPUTER. 2.54 multiplied by 43.5 = 110.49 centimeters. I WISH I COULD HAVE GONE TO THE COMPUTER TO HAVE SOMEONE DO MY HOME WORK FOR ME. I HAD TO FIGURE IT OUT ON A SLIDE RULE. DO YOU KNOW WHAT A "SLIDE RULE" EVEN IS??? EDIT: A "slide rule" is a non mechanical or digital calculator, and was the only thing available when I was in HS and college: http://en.wikipedia.org/wiki/Slide_rule Christopher K.
