Rip the 3/4-in. plywood to width for the case sides and shelves using a table saw or circular saw and straightedge guide. Crosscut the case sides to length, making them 2 in. shorter than the distance from the top of the base to the ceiling. Then, cut all the shelves to length. The shelves should be no longer than 36 in. to keep them from sagging under heavy loads. Before proceeding, finish all the plywood pieces.

Woodworkers use geometry, arithmetic, algebra, calculus, and statistics to measure materials and during the planning stages of projects.  On any given job, they will calculate sizes, dimensions, distances, and quantities of materials.  Computer skills and knowledge of relevant software also benefits woodworkers with job-estimating, project management, and basic spreadsheet or word processing.  Woodworkers should be detail-oriented, have good people skills, have steady hands, and physical strength, especially when lifting 100-pound sheets of plywood.
Another fine example of remodelling furniture and re-using what already exists in the house.  The bookcase involves using your old kitchen cabinets, and building new shelves on top of them. The final product can also be used as an entertainment unit, housing a television, books and things of your interest along with ample storage to keep other utility objects.
