Volume is the amount of space contained in an object.
We can find the volume of box shapes by the formula Volume = length x width x height
In this case the units would be cubic centimeters (cm3).
So a box 2 cm x 3 cm x 5cm would have a volume of 30 cm3
V = L x W x H
The base unit for volume is the Liter.
We measure volume with a graduated cylinder.
Liquids form curved, upper surfaces when poured into graduated cylinders
To correctly read the volume, read the bottom of the curve called the meniscus
When the metric system was created, they decided that 1 cm3 of water would equal 1 milliliter of water and the 1 mL of water will have a mass of one gram.
1cm3 water =1 ml of water = 1 gram
We can use water displacement to find the volume of objects that are not boxed shaped.
We can put water in a graduated cylinder. If a rock causes the level to rise from 7 to 9 ml, the the rock must have a volume of 2-mL.
1 cm3 water = 1 mL of water = 1 gram
So what would be the mass of 50 mL of water be?
So what would be the mass of 1 liter of water be?
1 L = 1000 mL so its mass would be 1000 grams or a kilogram.
Density is the amount of matter (mass) compared to the amount of space (volume) the object occupies.
We will measure mass in grams and
volume in ml or cm3
Density is mass divided by volume.
Density = mass/volume
Remember, all fractions are division problems.
Since the unit for mass is grams, and the unit for volume is ml or cm3, then the unit for density is g/ml, or g/ cm3
Formula wheels make it easy to solve density problems.
Cover the property you are trying to find, and do what is left over.
To find density, cover the word density. You have mass over volume remaining. So divide mass by volume to find density!
