Answer:[tex]V=2\ ft^3[/tex]
Step-by-step explanation:
Given
Length of fish tank [tex]L=4\ ft[/tex]
Width of fish tank [tex]W=18\ in\approx 1.5\ ft[/tex]
Height of fish tank [tex]H=3\ ft[/tex]
Fish tank is filled up to a height of [tex]h=4\ in.\approx \frac{1}{3}\ ft[/tex]
Now volume of water in fish tank [tex]=L\times W\times h[/tex]
[tex]V=4\times 1.5\times \frac{1}{3}[/tex]
[tex]V=2\ ft^3[/tex]
