The rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.
<h3>What is density?</h3>
The density of any substance is the ratio of the mass of substance to the volume of the substance and the unit will be centimeter cube.
The volume of the substance will be 3.60cm high × 4.21cm long ×1.17cm wide = 17.7 milliliters.
density = mass of substance / volume of substance
Substituting the value in formula
Density = 21.3g / 17.7 milliliters.
Density = 1.20 centimeter cube.
Therefore, rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.

There are several ways to give an object potential energy. One can move the object against the force of gravity to increase. One can also stretch an object out or put pressure on it.
Explanation:
During a chemical change, a new kind of matter is formed. Examples are combustion, rusting of iron, precipitation and souring of milk.
Here are some of the properties of chemical change:
- They are not easily reversible
- It leads to the production of new kinds of matter.
- It involves change in mass.
- It requires a considerable amount of energy.
