First lets define volume and formula.

Volume is the amount of space an object or material occupies. It is measured in cubic units.

A formula is a mathematical expression or representation of a principle or rule.

In our situation the formula for volume is length, times width, times depth.

Therefore, if we have a fish tank for example, that has a length of 5 ft., a width of 3 ft., and a depth of 2ft., it would have a volume of 30 cubic feet.

As for a lock, we know it is 261.8 meters long, 24.4 meters wide, and has a lift of 14.2 meters. What would be its volume? Use the formula to find out.

V= l x w x d

Do you know how many fish tanks we can fill with the volume of water that fills a lock during the locking procedure?

Lets write a formula and find out!

The volume of water that fills a lock divided by the volume of water in a fish tank equals the amount of fish tanks we can fill.

Wow! I have a feeling that we could fill a lot of fish tanks, Kuku.
