Answer

33.2 in (rounded)

Work Step by Step

85 cm to inches We’re changing from a metric length unit to a U.S. length unit. In the “Metric to U.S. Units” side of the table, you see that 1 centimeter = 0.39 inch. Two unit fractions can be written using that information.(1 cm)/(0.39 inch) Or(0.39 inch)/(1 cm). Multiply by the unit fraction that allows you to divide out centimeters (that is, centimeters is in the denominator). 85 cm * (0.39 inch)/(1 cm) = 33.15 inches = 33.2 in (rounded)
