you divide 310 by 2.54
you then have 122 inches, which you then divide by 12 to get the amount of feet
122/12=10.17 feet

First step convert 310cm to inches by dividing 310cm by 2.54 since there are 2.54 cm to an inch.

310/2.54 = roughly 122 inches in 310cm.

now convert 122 inches into feet by dividing 122 by 12 since there are 12 inches to a foot.

122/12= 10.17 feet

or you can do it in a single step since there is 30.48 cm to a foot. You can divide 310cm by 30.48

310/30.48 = 10.17 feet.

Going a step futher to get more accurate you can find out how many inches there are in 0.17 of a foot by multiplying 0.17 time 12 which giver you 2.04 inches.

making it 10 feet and 2 inches in 310cm.

First convert the centimeters to inches using 2.54 cm = 1 in, and then convert the inches to feet using 12 in = 1 ft. So divide by 2.54 to covert to inches, then divide by 12 to get the answer in feet.

You could use other conversion factors, but 2.54 cm / 1 in is the standard conversion factor for length, so anything else will be less approximate.

well you would say theres 310 cm and 2.54 cm in one inch. then theres 12 inches in one foot.
so divide 310 by 30.48 (30.48 is 12*2.54) and that would give you 10.17 ft.

1in= 2.54cm
12in= 1ft

310 cm (1 in/2.54 cm)(1 ft/ 12 in)

= (310)/((2.54)(12)) ft

= 310/30.48 ft

= 10.17 ft
