The answer to 7 feet 9 inches times 3 feet 10 inches? (7' 9" x 3' 10") is displayed below:
29.7083333333333 square feet
Here is how we calculated 7 feet 9 inches times 3 feet 10 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
7 feet 9 inches = 93 inches
3 feet 10 inches = 46 inches
Then, we multiplied 93 inches by 46 inches to get the total number of square inches:
93 x 46 = 4278 square inches.
Finally, we converted 4278 square inches into feet as follows.
4278/(12*12) = 29.7083333333333 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.
