The answer depends on the angle between the 9 ft length and the 21 ft length.
If the angle between the two is x, then
(diagonal)2 = [9 + 21cos(x)]2 + [21sin(x)]2 = 522 + 378*cos(x).
Therefore, 522-378 ≤ diagonal2 ≤ 522 + 378
that is 144 ≤ diagonal2 ≤ 900
or 12 ≤ diagonal ≤ 30
60.28 is the length of the diagonal, got through Pythagoras' Theorem.
To convert yards to feet, multiply by 3. So, the dimensions of the cuboid in feet are 9 ft x 21 ft x 27 ft. To find the volume, multiply these dimensions (9 x 21 x 27) to get 5103 cubic feet.
A 9 x 12 rectangle has a diagonal of 15.

About 8.5 feet.
The diagonal of a 46' x 46' square is 65.05 feet.
1 square yard = 9 square feetCost = (21 x 12) x 14.50 / 9 = 3,654 / 9 = $406
Since a square has right angles, you can use the Pythagorean Theorem to calculate the diagonal. Specifically, the diagonal of a square is equal to the length of a side, multiplied by the square root of 2.
(Diagonal)2 = (36)2 + (26)2 = 1,972Diagonal = sqrt(1,972) = 44.4072 (rounded)
I assume that you refer to a 12 ft x 12 ft 8 in square. The length of the diagonal is determined easily suing Pythororas's therem: Diagonal = sqrt[122 + (128/12)2] feet = sqrt(304.4... ) ft = 17.448 ft approx.
-12 = x+9 x+9 -9 = -12 -9 x = -21
