Question 744443
The problem states

A cylinder is 6 inches in diameter and 10 inches in height. It needs to be transferred into a rectangle and it has to have the same height and volume. 

volume of cylinder is pi*r^2*h
volume of rectangular l*w*h

volume of cylinder is 22/7 * 9 * 10 = 282.9 cubic inches

so we have for the rectangular solid

282.9 = l*w*10

28.3 = l*w

then you can pick any l and w whose product is 28.3
