Allan

Allan keeps tropical fish. His aquarium is 4 feet long, 1 foot wide, and 2 feet tall. Each fish needs at least 0.5ft³ of water. What is the maximum number of fish that he can keep in the aquarium? Please show your solution. Please

Correct result:

n =  16

Solution:

$$\begin{gathered} a=4\text{ ft } \\ b=1\text{ ft } \\ c=2\text{ ft } \\ {V}_1=0.5{\text{ft}}^3 \\ V=a\cdot b\cdot c=4\cdot 1\cdot 2=8{\text{ft}}^3 \\ {n}_1=V\mathrm{/}{V}_1=8\mathrm{/}0.5=16 \\ n=\lfloor n_1\rfloor =\lfloor 16\rfloor =16 \end{gathered}$$
