2,478
2,814

The correct answer is: 2,196

One cubic foot is equal to 12 inches by 12 inches by 12 inches, which equals 1728 cubic inches. Therefore, 13 cubic feet would be equal to 13 multiplied by 1728, which is 22464 cubic inches. Option A is incorrect because it is less than 22464. Option C is incorrect because it is more than 22464. Option D is incorrect because the product 13 multiplied by 12, 12, and 12 is not equal to 2,814. The correct answer is B because it is equal to 13 multiplied by 1728 and is the closest to the given options.
