You can either convert the feet and inches into inches or feet an fractions of feet. I suggest that you convert to inches, do the computation, then convert back to cubic feet. Nobody really likes to work with fractions if it isn't necessary. 2 ft 7 in = 31 inches 2 ft 8 inches = 32 inches 5 ft 7 inches = 67 inches Volume (cubic measurement) is found by multiplying the three dimensions (thus the name cubic) together. 31 in. X 32 in. X 67 in. = 66464 cubic inches No we convert back to cubic feet. To do this, divide the answer by 1728. Why? A cubic foot is 12 inches by 12 inches by 12 inches, or 1728 cubic inches. 66464 cubic inches / 1728 cubic inches = 39.462962962... cubic feet. These easily rounds to 39.5 cubic feet and is the most useful answer. If you want a precise answer, we need to convert the repeating decimal to a fraction. To do this multiply the whole number portion, 39, and the number you just divided by, 1728. This gives you 67392. In effect you "used up" 67392 cubic inches of the original 66464 cubic inches. You have 928 cubic inches left, not enough for another cubic foot. There has to be a fraction of a cubic foot left over. The fraction left over is the left over amount, 928 out of the original amount, 1728. Therefore the final answer is 39 and 928/1728 cubic feet. If you reduce the fraction to it's lowest term your final answer is 39 49/54 cubic feet.
Apples and oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot. 450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards. 450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.

There are approximately 460 cubic inches in a 289 that is bored 0.40 over. This can also depend greatly on what kind of weight the car is holding onto.
Boring a 396 engine 0.030 inches over increases its displacement by approximately 17.7 cubic inches.

If my math is correct : using a 4 inch bore and a 3.48 inch stroke , with the cylinders bored .060 , just over ( 360 cubic inches )
