Three boxes are stacked one on top of the other. One box is 6 feet 6 inches tall, one is 2 feet 11 inches tall, and one is 3 feet 9 inches tall. How high is the stack?
13 ft and 2 inches I believe Bc 6 + 2 + 3 = 11 (feet) Then 6 + 11 + 9 = 26 (inches) Then you need to convert the inches to feet giving you 2 more feet and 2 inches So 11 + 2 = 13 ft and 2 inches
