Answer: The tank which has 3 m side.

Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:

V = length*width*height

Since they are all the same, volume will be:

V = s³

One tank has a 3 m side, so its volume is:

V = 3³

V = 27 m³

The other has half of the first one side, then s = \frac{3}{2} and volume will be:

V = (\frac{3}{2})^{3}

V = \frac{27}{8} m³

As you can see, the volume of the second tank is \frac{1}{8} smaller than the first one. Therefore, the tank which has 3 m side can store more water than the  tank with side measuring half of the first.
