i hope this helps!!
Answer:
![V=45396.2\ cm^3](https://tex.z-dn.net/?f=V%3D45396.2%5C%20cm%5E3)
Step-by-step explanation:
Given that,
The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.
The tank is filled to 80% capacity with water.
We need to find the water needed for this tank.
The volume of cuboid is given by :
![V=lbh](https://tex.z-dn.net/?f=V%3Dlbh)
As it is filled to 80% capacity, so,
![V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B80%7D%7B100%7D%5Ctimes%20lbh%5C%5C%5C%5C%3D0.8%5Ctimes%2061%5Ctimes%2030.5%5Ctimes%2030.5%5C%5C%5C%5CV%3D45396.2%5C%20cm%5E3)
So,
of water is needed for this tank.
