measure the radius in feet( 1/2 the diameter) . multiply this number by itself (square it).
multiply this number by Pi ( 3.14). Measure the depth of the tank and multiply by your last answer and that's it in cubic feet.
706.5
40 sq ft
length x width = area (sq. foot)
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
545 tiles, as one tile is 1 sq. ft. Divide total square footage by 1.
3000 sq-ft multiplied by $10=$30,000 (you would multiply your square-footage by your cost per sq-ft)
A rug with a circumference of 6 ft has an area of 2.86 sq ft, approx.
well you multiply 150 times 3.99
Radius squared times pi 12X12=144X3.14=452.16 452 sq. ft.
You can't calculate linear footage based on square yardage alone. If you meant square footage it will cover 810 sq. ft..
Multiply the length by the width. i.e. 10' wide x 25' long... has an area of 250 sq. ft.
NO they differ by one dimension.
To calculate square footage you need to multiply the length by the width. L x W = Sq.Ft.
