AI explanation

The volume of the cube is found by cubing the edge length, giving 70 * 70 * 70 = 343,000 cubic inches. The volume of the solid cylinder inside the cube is calculated as pi * r^2 * h, which equals 22/7 * 20 * 20 * 70 = 88,000 cubic inches. To find the empty space, subtract the cylinder's volume from the cube's volume: 343,000 - 88,000 = 255,000 cubic inches.
