Which one is more accurate erlenmeyer flask or beaker?
Several things make volumetric flasks the most accurate way to measure volumes of liquids. First, they are specially calibrated and tested so that the volume listed is exactly the correct volume, often to within 0.01 mL. Secondly their shape is specially designed for accurate measurement. They have a long narrow neck with a line to mark the correct volume. Because the neck is so skinny, the water level is much more sensitive to the amount of water than if the neck was much wider (like in an erlenmeyer).Note that an erlenmeyer flask is about the worst thing I can think of to measure volumes! Much better than that is a graduated cylinder. A graduated cylinder, while somewhat less accurate than a volumetric flask does have the advantage of being able to measure different volumes, whereas a volumetric flask is designed to measure one and only one volume.
How do you measure volume of a material?
One way to measure volume of a material is the following: Put the material in a waterproof container, e.g. a tub. Submerge the material in water, register the water level, take the material out and measure what volume of water you need to add to the tub in order to make the water rise to the level it was with the material in. The volume of water you've added equals the volume of the material.
What is an easy way to measure the volume of an oddly shaped solid object?
by measuring the amount of water it displaces
What pieces of lab equipment measure volume?
There are three ways to measure volume. If you are measuring a liquid, you need a graduated cyliner. If you are measuring the volume of a regular solid, you need a ruler to measure length, width, and height. You would then use the formula V=LxWxH. The third way to measure volume is to use displacement to find the volume of an irregular solid. You would put a certain amount of water in a graduated cylinder, write the starting amount down. Add the irregular solid to the graduated cylinder. Record the ending amount of liquid and subtract the ending amount minus the starting amount.
How many millimeters in one third cup?
Liquids cannot really be measured in millimeters. Millimeters are a measure for length. Liquids are best measured by volume. In the metric system, milliliters are a very nice way to measure volume. There are 236.6 (two hundred thirty-six point six) milliliters in a cup of water.

How can a human find out his own volume?
Water displacement. get in a tub of measured water, mark where water level is when fully submerged, measure difference. Simplest if not the most accurate way of doing something.

Eyeballing it with a tape measure (not the most scientifically accurate way to measure it) I get 2.75 inches
Is a kite an accurate or inaccurate way to measure distance?
A kite is an accurate way to measure distance because of the long line that produces more accurate results.
What is the most accurate way to measure for custom draperies?
The most accurate way is to make a sketch of the window on a seperate sheet of paper, than measure the opening of the window, then the space between the top of the window and the ceiling, then the bottom of the window to the floor, and lastly the space on either side of the window.
How do you measure volume of prisms?
Assuming the cross-section of the prism is such that its area is easily calculated, Volume of prism = Cross-sectional area * length If not, the most effective way is to submerge it in water and measure the volume of water displaced.
What can you measure a lb of horse feed with?
If you want to measure a pound of feed for a horse, it is a good idea to use a scale. A scale will be the most accurate way to measure a pound of feed.
How do you measure the volume of?
If the object is irregular the best way is to measure the volume of water it displaces when you immerse it completely in water.
How do you measure the volume of an object that was NOT a rectangular prism?
One way to measure the volume of an irregular object is to use a graduated cylinder. Fill the cylinder about half-way with water, and measure the volume. Then, place the object in the cylinder and measure the new volume. Subtract the first from the second to find the change in volume of the water. This change in volume is the voume of the object. Unfortunately, this method will not work for all objects as some are to large to fit in a graduated cylinder and some will dissolve in water, but it is very usefull in most situations.
How do you measure the volume of object?
If the object is irregular the best way is to measure the volume of water it displaces when you immerse it completely in water.
