Answer:
Volume of the cube = 91.125 cubic feet.
Step-by-step explanation:
Given : A fish tank is a cube. its side length is 4 1/2 feet.
To find : Volume of water needed to completely fill the fish tank is cubic feet.
Solution : We have given
Side length of cube = \(4\frac{1}{2}\) = \(\frac{9}{2}\) feet .
Volume of the cube = \(Side^{3}\).
Plug the value side length = \(\frac{9}{2}\) .
Volume of the cube = \((\frac{9}{2}) ^{3}\).
Volume of the cube = \(\frac{729}{8}\) .
Volume of the cube = 91.125 cubic feet.
Therefore, Volume of the cube = 91.125 cubic feet.
