You don't measure volume with a ruler. You measure length with a ruler.
To get volume, you will have to calculate it. Length X Width X Height.

The reason its harder to measure volume with a ruler is because rounded surfaces can't easily be measured. If you had a cube you could measure the length, width, and height and get an accurate volume. But say you were trying to measure the volume of a basketball. it wouldn't be very easy to measure with a ruler.

rulers measure length.
To find the volume of say a cup of water, it would be best to pour it all into a graduated cylinder.
However, if you only have a ruler, you will also require a perfectly rectangular glass cup to hold your liquid, and then measure the length, width and height of the water held in the container. If you have the cubic cm, you can then convert to milliliters. 1 ml = 1 cubic cm.
This is why it is harder to use a ruler to measure volume, because volume is in three dimensions, and rulers meausre only length which is 1 dimension.

Because you have to measure three times to find volume with a ruler (length, width and height). Rulers only measure one dimension at a time. For volume, you need a device that can measure three dimensions simultaneously.
Seriously, thats about the best answer anyone can give to that question.

Well not every substance's volume can be measured with a ruler... like a very bumpy rock... you'd have to measure the size of each bump, every crack and corner of it. Using a ruler is best executed when you measure a block or something similar.

a ruler is a 2 dimensional measuring instrument, calibrated to measure a single dimension at a time and it will have to be used 3 times to measure volume since it is in three dimensions.
There are instruments calibrated to measure volume directly like a graduated cylinder or beaker.

you should use the lines on your graduated cylinder because when you use a ruler you are calculating the volume of the liquid plus the glass. Also glass bends light and your lines wont be entirely accurate

Ruler = find length and height
Length = find surface area
Volume = surface area x height
No chemistry involved... elementary my dear

Naughty Nurse is a plagiarist. Are you talking about measure theory and probability?

heres a thought..... re read the text book.... conclude your answer from what you read.... you can not learn the material if you do not take the time to study it. Comprehension and Astute attention makes a better Student.
