Question

the principal is measuring the floor of the second - grade classroom. what is the best estimate for the length of a classroom? 10 yards 10 inches 10 centimeters 10 feet

Explanation:

10 inches and 10 centimeters are too small for a classroom length. 1 yard = 3 feet, 10 yards = 30 feet which is a bit large for an average - sized second - grade classroom. 10 feet is a more reasonable estimate.
