Answer:
A. (1 2/3, 4 2/3)
Step-by-step explanation:
If you graph the equations, you see the lines intersect at the solution point:
(x, y) = (1 2/3, 4 2/3)
To find volume you just multiply the length, width, and height, so 15,000 cubic feet.
Any point on the x-axis beyond the point (4, 0) is a possible cordinate of R.
