To find the answer multiply the length by the width. In this case 3 feet times 10 feet is 30 square feet.
10 x 10 = 100 square feet.
There are 10 times 10 = 100 square feet
on a wall it would be 100 square feet.
8' x 10' = 80 square feet
It is 16 times 10 = 160 square feet
10 feet
24 feet x 10 feet = 240 square feet.
800 feet / 10 foot per board = 80 boards
That's a total of 100 square feet (100 ft2)
10 feet 1 yard=3 feet. 3 yards=9 feet. 9 feet + 1 foot = 10 feet
One foot is 30.48 centimeters.
93 square feet.
