Answer:
The height of the rock is 15 mm.
Step-by-step explanation:
Given : Cristian put a large rock on the bottom of the terrarium he made for his pet turtle.
To find : How high is the rock?
Solution :
The rock is a right rectangular prism 10 cm wide by 12 cm long.
Let the height be 'h'.
The volume of the right rectangular prism is ![V=L\times B\times H](https://tex.z-dn.net/?f=V%3DL%5Ctimes%20B%5Ctimes%20H)
i.e. ![V=10\times 12\times h](https://tex.z-dn.net/?f=V%3D10%5Ctimes%2012%5Ctimes%20h)
![V=120h](https://tex.z-dn.net/?f=V%3D120h)
The rock displaces 1800 cm³ of water.
i.e. The volume of the right rectangular prism is equal to the rock displaces of water.
So, ![120h=1800](https://tex.z-dn.net/?f=120h%3D1800)
![h=\frac{1800}{120}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B1800%7D%7B120%7D)
![h=15](https://tex.z-dn.net/?f=h%3D15)
Therefore, the height of the rock is 15 mm.
