There is no conversion. Cubic feet is for volume while square feet is for area.
A cubic foot is a square, 1ft by 1ft by 1ft. It is equal to 1728 cubic inches or 12x12x12. If you had one square foot with something one foot high occupying the one square foot area, you would have 1 cubic foot. cubic feet measures volume, square feet area, and just plain feet or linear feet distance.
The formula for Cubic Feet is: Length × Width × Height. For example, a 600 square foot room with a 10 foot ceiling would be 6000 cubic feet.
A square foot is a unit of area. A cubic foot is a unit of volume. The two units are therefore incompatible.
There are 144 square inches in a square foot and 1.728 cubic inches in a cubic foot. So you have 7,776 square inches and that would give you 7,776 cubic inches. That would be 4.5 cubic feet.
40 square feet
There are an infinite number of square feet in a cubic foot. This is because a square foot defines a 2D plane, and 2D objects have no depth. They are infinitely thin and therefore there would be an infinite number of square feet in a cubic foot. This is equal to asking how many 12 inch line segments are in a square foot, or to the next dimension, how many 12 inch line segments are in a cubic foot. Same answer, infinity.
A 2x12x12 foot board would not be measured in square feet but cubic feet and there would be 240 feet3
Convert everything to cubic feet. It should be easy then. Since one yard = 3 feet, 1 cubic yard = 27 cubic feet; also, one square foot x 1/4 foot = 1/4 cubic foot.
27 cubic feet = 1 cubic yard4 inches = 1/3 foot(81 square feet) x (1/3 foot) = 27 cubic feet = 1 cubic yard
48 by 23 by 20 whats? The answer will come out to cubic feet, not square feet. There are 1728 cubic inches in a cubic foot, so the answer is on the order of 12.78 cubic feet.
ONE I THINK, SINCE THERE ARE 27 CUBIC FEET IN A CUBIC YARD OF CONCRETE (WHICH MEASURES 3 FEET BY 3 FEET BY 3 FEET).
