If something seems light for its size (like a bag of cotton or pumice rock), then we say it has low density. Mass is the amount of matter in an object. Volume is how much space ... of different ...

We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example, the iron cube has a volume of 8 cm³ and a mass of 63 g, so: A typical neutron ...

Show the Animation – Density: Wood and Water If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that ...

To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The ...
