Taking into account the change of units, 21.8 in³ is equal to 0.357238 L.
<h3>Definition of rule of three</h3>
The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied using the following formula, where a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: x= (c×b)÷ a
The direct rule of three is the rule applied in this case where there is a change of units.
<h3>in³ to liters</h3>
To perform in this case the conversion of units, you must first know that 1 in³ = 0.0163871 L. So, the rule of three can be used as follow: if 1 in³ is 0.0163871 L, 21.8 in³ equals how many L?
1 in³ ⇒ 0.0163871 L
21.8 in³ ⇒ x
So: x= (21.8 in³ ×0.0163871 L)÷ 1 in³
Solving:
<u><em>x= 0.357238 L</em></u>
In summary, 21.8 in³ is equal to 0.357238 L.

Answer: The layers of the rocks in one region of the parks are smooth and distinct, which are evidence of many, many years of deposition. The layers on the rocks are because of different deposition of sediments. Different sediments deposited over the rocks through wind, water and ice over the ages
