Q&A for How to Convert Square Feet to Cubic Feet

They are different things entirely. A square foot is a two-dimensional measurement, whereas a cubic foot is a three-dimensional measurement (e.g. the volume of a room). One is not convertible to the other.

You would need an additional measurement, such as height or depth. Without that third measurement, square feet are not convertible to cubic feet.

Decide how deep you want to spread the topsoil. Multiply the depth by the area you're covering. That gives you the volume of topsoil you need.

Divide cubic feet by a linear dimension (width, length, or height).

Cubic feet and square feet are not convertible to each other. The first is a measure of volume; the second is a measure of area.

If you're going to deal with the volume (cf) of each bag, you will need to know the volume of the storage area. If you're dealing with the area (sq ft) of the storage area, you will need to know how much area each bag takes up (in sq ft).

No, that item is well over 4 cu ft.

There are various (slightly different) definitions of a cubit, but it's commonly thought of as 18 inches.

If you mean 78 square feet to be covered by 2 feet of mulch, the volume is 156 cubic feet.

Multiply 200 square feet by one-twelfth of a foot (one inch) to get the volume. That's the same as dividing 200 by 12: 16 2/3 cubic feet.

Multiply the number of square meters by 10.764.

2 inches is 1/6 of a foot. (320 square feet)(1/6 foot) = 53.33 cubic feet.

It depends on the density (weight) of the material involved. For example, if a cubic foot of the material weighs ten pounds, 350 cubic feet of that material would weigh 3,500 pounds.

1 foot equals 3.048 decimeters. 1 square foot equals (3.048)² = 9.29 square decimeters. 1,100 square feet equals 10,219 square decimeters.

Assuming the container is cylindrical (with a radius of 10½ inches), the volume formula is πr²h = (3.14)(10½)²(18) = 6,231.33 cubic inches = 3.6 cubic feet.

Divide the circumference by pi. That's the diameter. Divide by 2. That's the radius. Square it and multiply by pi. That's the area of the circular base in square inches. Multiply by the length. That's the volume of the cylinder in cubic inches. Divide by 1,728. That's the volume in cubic feet.

It depends on the shape - follow the instructions for the shape you're working with. If it's a simple rectangular prism, just multiply 6800 by the height or whichever dimension wasn't used for the area.

Yes.

"Square footage" would refer to the area of one or more surfaces of a cube. To find the square footage of a side of a cube, square the length of one of its edges, measured in feet (that is, multiply an edge length by itself). (If you're actually asking about "cubic footage" of a cube, find that by cubing an edge length, expressed in feet -- that is, multiplying an edge length by itself and then multiplying a second time by that length.)
