1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok
Each tile is 12 inch x 12 inch = 1 foot x 1 foot = 1 square foot. To cover 240 square feet you would need 240 tiles
A 12x12 inch paver is one square foot. So you would need 240 square feet.
24 feet x 10 feet = 240 square feet.
The area of 12 foot times 20 foot are 240 square feet.
Linear feet measure length, square feet measure area. Comparison is therefore meaningless.
If the size is 30 inches x 8 inches then the area = 30 x 8 = 240 square inches. If the size was in feet, multiply 240 by 144.
A 2x12x12 foot board would not be measured in square feet but cubic feet and there would be 240 feet3
usually 20 btu's per square foot so......12000 btu's should do fine
6x3 would require 2 pavers by 4 pavers to make a square foot which is 8 pavers per square foot. 240 pavers. That's only a 5 foot by 6 foot square.
If the dimensions given are in feet then: 60*48 = 2880 square feet
That is 240 square inches. There are 144 square inches in a square foot therefore it is approximately 1.66 square feet.
