A 6.00 ft by 8.00 ft bookcase is to be built. It has horizontal shelves every foot. A support is to be notched in the shelves diagonally from one corner to the opposite corner. (Round your answers using the rules for working with measurements.)
At what point should each of the shelves be notched? That is, find lengths A, B, C, D, and E (in ft) in the figure.
How long (in ft) is the crosspiece?
