Feet and Inches Conversion Practice Test

You and a friend build a treehouse platform that is 6 ft long. You measure carefully so the wood fits well. You remember that 1 ft equals 12 in. The floor boards must match the platform length exactly. How many inches are in 6 ft?

You build a treehouse ladder that measures 3 ft 6 in. You want to write the length in inches only. You use 12 in for each foot. The hardware store asks for the ladder length in inches. Convert 3 ft 6 in to inches.
