Video Summary

Bob needs to complete a square using rectangular pieces. The three known pieces sum to 24 blocks, and the total must fit into a 6x6 square, meaning 36 blocks are needed. The solution options are A (15), B (5), C (6), D (12), and E (12). Since only 12 more blocks are needed to complete the square, D and E are valid candidates. By examining how the pieces fit together to form the square, option E fits correctly when rotated 90 degrees. Therefore, the fourth piece Bob uses is option E.
