9. We're assuming this block of wood is a rectangular prism. Therefore: V = lwh. 4.5 * 3.5 * 7 = 110.25.
10. I cannot solve the problem because all dimensions are not shown.
11. Rect. prism A is 120. Rect. B is 960. To find how many times greater B is than A, 960/120 = 8.
12. See 10.
13. V = lwh. 6.5 * 2.5 * 4 = 65. 65 * 0.9 = 58.5.
Hope this helps!
