One way to obtain cubic feet (CF) is to multiply length in feet * width in feet * height in feet (L*W*H=CF).
To break CF down into x dimensions, divide CF by known dimensions. You need to know two of the dimensions to calulate the third dimension. If you know only one, you can obtain the square footage of the remaining two sides.
If you know two of the three dimensions, say the height and width, rewrite the formula into ((CF/H)/W)=L.
An example would be a box that has the capacity to hold 7 cubic feet. If you know the height of the box, say it's 1.75 feet, divide 7 CF by 1.75'. The answer would be the square feet of the bottom, which would be 4 SF.
If you also know one side of the bottom, say the width is 1.5', the remaining side is 2.67' (4 SF/1.5'=2.67').
