Answer:
[tex]V=45396.2\ cm^3[/tex]
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 :
[tex]V=lbh[/tex]
As it is filled to 80% capacity, so,
[tex]V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3[/tex]
So, [tex]45396.2\ cm^3[/tex] of water is needed for this tank.
