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

Answer:
The volume of the 50% solution used is 0.8 gallons and the volume of 25% solution used is 1.2 gallons.
Explanation:
Let the volume of the 50% solution be be x gallons.
Let the volume of 25% solution be y gallons.
Total volume of the solution after mixing above volumes of the solutions = 2 gallons
x gal + y gal = 2 gal
...[1]
Percentage of the final salt solution = 35%
....[2]
On solving [1] and [2] , we get:
x = 0.8 , y = 1.2
So, the volume of the 50% solution used is 0.8 gallons and the volume of 25% solution used is 1.2 gallons.
Answer:
The correct answer is D.
Glaciers fall into two groups: alpine glaciers and ice sheets. Alpine glaciers form on mountainsides and move downward through valleys. The largest ice sheets, called continental glaciers, spread over vast areas. Today, continental glaciers cover most of Antarctica and the island of Greenland.
