About 28.28 ft. You can solve this as a right triangle problem. Multiply each side x itself (square it) that Is 400. Add the squares of the two sides (400+400= 800). Then find the square root of 800, which is 28.28
A measurement of 400 square feet is an area which is measured by multiplying the width by the length to reach a total of 400. An area 10 feet by 40 feet would be equal to a total of 400 square feet.
None ... gallons is a measurement of volume, square feet is area not volume.
It is exactly 400 square feet.

Assuming your measurement is in feet - 400 square feet of timer.
Just multiply the two together. This would give you 400 square feet.
A linear inch is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.
Just about 400
It is exactly 400 square feet.
400 square feet
400 by 400 feet = 160,000 square feet 160,000 square feet = 3.6730946 acres
400 square ft = 37.16 square m
I'm going to say 400.
