Answer: The method used to measure an irregular solid by placing it inwater is called dispersion. If you note the level of the waterbefore placing the object in and the level after, you can find thevolume of the object by calculating the difference.
Answer: Yes, It uses more energy to use it at high volume then if you were using it on low
If you have a car and a very large open area and maybe a few car batteries time the car on cranked volume for 1st batterie. Next use the next of the batteries and use low volume. (the high volume is going to "die" first)
Answer: Volume in math means the amount of space an object occupies.Volume in music means amplitude, loudness, or sound pressure.Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?".
Answer: It is best if u know the diameter or the circumference. then u can dip a rod into it and see the height of the oil on the rod after removing it. calculate the volume of cylinder as u know the parameters. offcourse do a bit work to find the formula its easy. it this is NT possible see the holding capacity of the tank. and dip the rod again see the level. its gives estimated but useful information and prevents ypur vehicle from getting out of fuel!!!
