To convert square feet you multiply by the height.
Example 1 - if you are trying to find the cubic feet in a home that has 8 foot tall rooms it would be 4,000 square feet X 8 feet = 32,000 cubic feet
Example 2 - if you are trying to find the cubic feet in a flower bed 6 inches deep it would be 4,000 square feet X 0.5 feet = 2,000 cubic feet
You don't, square feet are a measure of area and cubic feet are a measure of volume.
You simply can't convert square units to cubic units.
You can't convert that. You can convert linear units to linear units, square units to square units, or cubic units to cubic units.
You don't. You either A) convert 18 cubic inches into cubic feet, or B) convert 18 square inches into square feet. A... there are 1728 cubic inches in a cubic foot, so 18 cu in would be 0.00104 cu ft. B... there are 144 square inches in a square foot, so 18 square inches would be 0.125 sq ft.
You cannot do that since cubic yard is volume and square foot is area. You need to know the thickness
you'll need 24.69 cubic yards, That's 4000 * (2/12) / 27 This is because there's 12 inches in one foot and 27 cubic feet in 1 cubic yard.
You cannot directly convert square feet to cubic feet, as they measure different things. Square feet measure area, while cubic feet measure volume. To convert square feet to cubic feet, you would need a third dimension, such as height or depth.
To convert square feet to cubic yards, you need to know the height or depth of the space. Without that information, it is not possible to accurately convert 308 square feet to cubic yards.
To convert dollars per square foot to dollars per cubic yard, you need to consider the dimensionality difference. Since square feet are 2-dimensional measurements and cubic yards are 3-dimensional measurements, you would need to know the height or thickness of the object to make an accurate conversion. Once you have the height or thickness, you can use the conversion factor to calculate the cost per cubic yard.
Square foot is a measure of area. Cubic foot is a measure of volume. They are not equal.
To convert square feet to cubic feet, you need to know the height or depth of the space. If the height is 1 foot, then 400 square feet would equal 400 cubic feet. However, if the height is different, you would need to multiply the square footage by the height in feet to get the cubic footage. For example, if the height is 10 feet, then 400 square feet would equal 4000 cubic feet.
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.
