Question

30 POINTS !!!!!!

Answer 1

I know it's only 5 points but heres the answer
 1. It depends what type of method you are using. if it is Height x Width x Length then it will not work for an irregular shape because it has extra pieces that would not be included. 

2. The second method would work for both regular and irregular shapes because you would have to know or find out the volume of the regular shape to get the volume for the irregular shape. 

3. It also depends on what you are doing, if you are doing a regular shape then use the first method, if it's an irregular shape then use the second method, if you do the maths correctly both should give you an accurate answer for what you want to achieve. 

4. No, because the sugar would dissolve. 

5. No, on this case the displacement method would not work because of the weight difference 

I hope this helps you a bit.
