Answer:
igneous rock
Explanation:
There are three main kinds of rocks, sedimentary, metamorphic and igneous.
The igneous rocks are the ones that formed from a hot source like magma inside the soil, as it gets to the surface of the Earth it goes cooling. If it cools almost in the surface of the Earth then is consider a plutonic rock.
Plutonic Rocks have a big quantity of minerals, since they cool under a big pressure, these minerals get together forming a solid rock.
By passing the time the granites of minerals can be easily seen at naked eye, like the characteristics of these sample.
The answer to the question is the total surface area increases and chemical composition changes. Consider the breakdown of rock into smaller pieces, these fragments vary from huge rocks to smaller sizes. As they are so crushed and broken they tend to occupy much of the surface area than when its just a huge rock.
First turn 18% to a decimal, which is .18, then multiply it by 450.
450 x .18 = 81
