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?
The shoebox is 24 square inches because 4 x 6 = <<4*6=24>>24
The block is 16 square inches because 4 x 4 = <<4*4=16>>16
There are 8 square inches uncovered because 24 - 16 = <<24-16=8>>8
