every cube 1/6 of an inch. there are 12 cubes and length of each cube is 1/6 inch. to find the total length, lets multiply 1/2 with 12. the answer is 2. this means total length is 2 inches. now for the width...there are 3 cubes each of 1/6 inch side length. so to find total width we'll multiply 3 with 1/6 and the answer is 1/2. now for the height there are 2 cubes each of 1/6 inches...to find total height...multiply 1/6 with 2 and the answer is 1/3. now to find the volume, multiply the values of lenght, width and height that we just calculated. the answer is 1/3, Btw i See you are a Albert fan his birthday is before mine.
