Building a pyramid out of legos... Using rectangular legos that are four bumps by two bumps. It was started with one lego in the top level. Underneath was as many legos as needed to leave one row of bumps all the way around the outside. Continuing to build the pyramid in such a way that there was always one row of bumps all the way around the outside on each level. In the end it can make 10 levels. The pyramid is completely filled with legos many of which are not visible from the outside. How many legos are in the pyramid and how many bumps total on all the levels that are visible on the outside of the pyramid? HELP!!! I even tried doing it with Brock's legos.
