Question 973088
.
In the rectangular tank (3'long x 4'wide x3'high), each inch of height contains:
{{{(3ft)(4ft)((1/12)ft)=1ft^3}}}
For each inch in height the tank contains 1 cubic foot of water.
From the square tank:
{{{(3ft)(3ft)(3ft)=27ft^3}}}
The 3 foot cube contains 27 cubic feet of water, so the water would be 27 inches high in the rectangular tank.
