The answer to 9 feet 11 inches plus 8 feet 6 inches (9' 11" + 8' 6") is displayed below:
18 feet 5 inches
Here is how we calculated 9 feet 11 inches plus 8 feet 6 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
9 feet 11 inches = 119 inches
8 feet 6 inches = 102 inches
Then, we added the inches together to get the total number of inches:
119 + 102 = 221 inches.
Finally, we converted 221 inches into feet and inches to get the answer.
9' 11" + 8' 6" = 18' 5"
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches, and
to make it back to feet and inches we divided total number of inches by 12.
