Graphically, a point is a solution to a system of two inequalities if and only if the point lies in the shaded region of the top
inequality, but not in the shaded region of the bottom inequality. lies in the shaded region of the bottom inequality, but not in the shaded region of the top inequality. lies in the shaded regions of both the top and bottom inequalities. does not lie in the shaded region of the top or bottom inequalities.
Ok so you need to multiply the length, width, and height together for each one. Bill: 8 x 20 x 6 = 960 Martin: 4 x 15 x 16 = 960 So Bill is right, they both have the same volume.
