Answer:

108, 460, 1,680, 12,960, 2,299, and 128. num. 7: 329.7

Step-by-step explanation:

the formula for volume is LxWxH so multiply all of them together and you get the answer which is in the answer section above. a thing to note is that num. 2, you need to find the diameter so that's 20 then multiply. for 7, multiply 5 and 42(got this by adding 21 plus 21 to find the diameter) then multiply 3.14 which is again in the answer box.
