10' x 15' x 8' = 1,200 cubic feet.
1 cubit = 1.5 feet so 27 cubit feet is an area of 40.5 square feet.
A cubit = 1.5 feet so a cubit foot is a measure of area in 2-dimensional space. There is no measure of volume and therefore there is no value which can be assigned.
There are 3 cubit feet in 1 cubit yard. Although irrelevant in this context, you may wish to know that 1 cubit = 1.5 feet = 0.5 yards.
