This is not a valid conversion. Cubic units is a measure of volume while square units is a measure of area.
If the container is 1 inch deep, the area is 1 square foot.
You don't, square feet are a measure of area and cubic feet are a measure of volume.
There is no conversion. Cubic feet is for volume while square feet is for area.
square feet
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.
"Square cubic foot" or feet doesn't make sense. Either you have square feet, or cubic feet.
Assuming the container is full at 1500 liters, the container's volume in cubic feet will be about 53 cubic feet (52.9720005, more precisely).
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.
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.
For General.A (gallon) is a fluid measurement, and a (cubic foot) is a volume measurement. So to measure a gallon, you need to measure the square in. of container (use container that measures the same square in. from bottom to top), then pore in one gallon of any liquid and measure the hight it comes; multiply this by square in. of container and you have your cubic inches in that gallon. For Water.One gallon equals 0.134 cubic feet. This is granted that the water remain at constant temp., and at a point to have the stated volume.
That would be very difficult to determine. The experiment could never be set up and conducted, since there is no such thing as a "cubed square foot". If you meant to say cubic foot, then here is a way to determine it. You will need golf tees that will sink in water, plus a container holding 2 cubic feet, with a mark at the one cubic foot level. Fill the container with water to the one cubic foot level. Start dropping in the golf tees until the water level is at the top, or two cubic feet. Count how many golf tees you put into the container to get your answer.
