Tara has a shoebox that is 4 inches tall and 6 inches wide. She puts a square block inside that is 4 inches per side. How many square inches of the box are left uncovered? Let's answer step by step:
The shoebox is 24 square inches because 4 x 6 = 24. The block is 16 square inches because 4 x 4 = 16. There are 8 square inches uncovered because 24 - 16 = 8. The answer: 8.
