Answer 1

Answer:  5000

Step-by-step explanation:

Let L and H represent length and height, respectively.

.. 20 ft = (4/5)*L

.. L = (5/4)*(20 ft) = 25 ft . . . . . . . . multiply by the reciprocal of the coefficient of L

.. H = (2/9)*(L +20 ft)

.. = (2/9)*(25 ft +20 ft))

.. = (2/9)*(45 ft) = 10 ft

The volume is the product of length, width, and height.

.. V = (25 ft)*(20 ft)*(10 ft) = 5000 ft^3
