A builder wants to build a corbeled arch, based on the principle of stability, what minimum number of bricks, each 0.30 m long, is needed if the arch is to span 1.0 m? Be sure to include in the total number of bricks one brick on top and one brick at the base of each half-span of the arch.

Question

I really need some help figuring out the process for this problem. I know that the answer is 35, but I don't know how to go about finding that answer. Any and all help is very much appreciated! Thanks.
