Question

PLEASE HELP ASAP

Answer 1

I believe you meant:

0.5 fish

------------

ft^3

instead of:

The density of a fish tank is 0.5 \frac{fish}{feet} ³. fish^3 has no meaning. ;)

Try this:

30 fish

-------------------- = 60 ft^3. If the tank were a cube, it'd have side length 3.9 feet.

0.5 fish / ft^3
