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 = [tex]4\frac{1}{2}[/tex] = [tex]\frac{9}{2}[/tex] feet .
Volume of the cube = [tex]Side^{3}[/tex].
Plug the value side length = [tex]\frac{9}{2}[/tex] .
Volume of the cube = [tex](\frac{9}{2}) ^{3}[/tex].
Volume of the cube = [tex]\frac{729}{8}[/tex] .
Volume of the cube = 91.125 cubic feet.
Therefore, Volume of the cube = 91.125 cubic feet.
