The volume of the water tower can be calculated using the formula V = lwh, where l is the length, w is the width, and h is the height.

Given information:
Width = 16 meters
Height = 25 meters

Using this information, we can calculate the volume:

V = (16)(25)(h)
V = 400h

To find the volume, we need to know the length of the water tower. Without the length, we cannot calculate the volume accurately.

Therefore, the volume of the water tower cannot be determined with the given information.

You would need to know the length of the water tower to accurately calculate its volume.
