A box of books has a mass of 4.10 kilograms for every meter of its height. Convert this ratio into pounds per foot.

Hello User,

2.76 lb/ft

Steps:

This is a simple matter of multiplying and dividing by the appropriate conversion factors. You're highly unlikely to find a table of conversion factors for exactly this conversion so I'll demonstrate the conversion using 2 simple conversion factors. The conversion from meters to feet, and kilograms to pounds x = 4.10 kg/m * 2.20462 lb/kg / 3.28084 ft/m x = 9.038942 lb/m / 3.28084 ft/m x = 2.755069 lb/ft Since we have only 3 significant digits, round to 3 digits. x = 2.755069 lb/ft x = 2.76 lb/ft
