A lumberyard charges $ 1 per cut to trim boards. Bob buys a 12-ft board and wants it out into twelve 1-ft pieces. How much will he be charged for the cutting? The correct answer is $11.
The better answer would be closer to $4, if they have a bigger saw. Cut it in half, stack the halves, cut those in half, stack the quarters and cut them all into 3 pieces, giving you 12 pieces with 4 cuts. I do this with firewood on a regular basis.
