There can be no conversion.
A linear foot is a measure of length in 1-dimensional space while 4 ft x 3 ft is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
There are linear feet, and square feet, but no "linear square feet".
72 feet is already linear as feet is linear so answer is 72
Feet and linear feet are the same measurement. Therefore, 500 linear feet is equal to 500 feet.
Feet and linear feet are the same measurement. Therefore, 60 linear feet is equal to 60 feet.
A foot IS a linear measure so a foot is a linear foot. So 84 linear feet is 84 feet.
Linear feet are the same as feet, so the answer is 133 linear feet!
There are linear feet, and square feet, but no "linear square feet".
50 feet is equal to 50 linear feet. The measurement of feet is the same as linear feet in this case.
72 feet is already linear as feet is linear so answer is 72
Feet and linear feet are the same measurement. Therefore, 500 linear feet is equal to 500 feet.
Feet and linear feet are the same measurement. Therefore, 60 linear feet is equal to 60 feet.
A foot IS a linear measure so a foot is a linear foot. So 84 linear feet is 84 feet.
Feet and linear feet are the same measurement - linear feet is merely a name to reduce confusion between them and square feet. Therefore, 52490 feet is equal to 52490 linear feet.
Feet are the same as linear feet. Linear just distinguishes them clearly from square feet or cubic feet.
Feet and linear feet are the same measurement. Therefore, 10 linear feet is equal to 10 feet.
Feet and linear feet are the same unit of measurement. Therefore, 800 linear feet is equal to 800 feet.
is 8 feet 8 feet in linear feet
