The answer to 8 feet 6 inches times 8 feet 9 inches? (8' 6" x 8' 9") is displayed below:
74.375 square feet
Here is how we calculated 8 feet 6 inches times 8 feet 9 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
8 feet 6 inches = 102 inches
8 feet 9 inches = 105 inches
Then, we multiplied 102 inches by 105 inches to get the total number of square inches:
102 x 105 = 10710 square inches.
Finally, we converted 10710 square inches into feet as follows.
10710/(12*12) = 74.375 square feet
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches.
Since we have both height and length in square inches, we divided by 12X12.
