Answer:
14 cm.
Explanation:
We have been given that Martene got an aquarium in the shape of rectangular prism with sides 18.5 cm long and 15 cm wide. Martene put
of water in the aquarium. We are asked to find the depth of the water.
We will use volume of rectangular prism formula to solve our given problem.
, where,
l = Length of base,
w = Width of base,
h = Height of prism.
Upon substituting our given values in above formula, we will get:
![3885\text{ cm}^3=18.5\text{ cm}\cdot 15\text{ cm}\cdot h](https://img.qammunity.org/2020/formulas/mathematics/high-school/kdra460b57fty9rke6wcohn0mr8g9xj70r.png)
![3885\text{ cm}^3=277.5\text{ cm}^2\cdot h](https://img.qammunity.org/2020/formulas/mathematics/high-school/txzqod3cb3u1vma5z7fhioousjerjb413l.png)
![\frac{3885\text{ cm}^3}{277.5\text{ cm}^2}=\frac{277.5\text{ cm}^2\cdot h}{277.5\text{ cm}^2}](https://img.qammunity.org/2020/formulas/mathematics/high-school/iop6h7hga0mgg01r5n5foewt4ohqhxv37f.png)
![\frac{3885\text{ cm}}{277.5}=h](https://img.qammunity.org/2020/formulas/mathematics/high-school/ve8v7u6fs16huexve32g1hqdb1v16sfv45.png)
![14\text{ cm}=h](https://img.qammunity.org/2020/formulas/mathematics/high-school/qrl9rzy3qey4zjklt9ls2jpo1ibqjcdo9g.png)
Therefore, the depth of the water in the aquarium is 14 cm.
