The swimming pool that Calvin goes to has dimensions 20 meters long, 8 meters wide and 3 meters deep. What is the volume of water (in m3) that the swimming pool contains?

Assuming that you fill it right to the top:

20 * 8 * 3 = ?

To find the volume of water in the swimming pool, you need to multiply its length, width, and depth together. The formula for volume is as follows:

Volume = Length × Width × Depth

In this case, the length of the swimming pool is 20 meters, the width is 8 meters, and the depth is 3 meters.

Substituting these values into the formula, we get:

Volume = 20 meters × 8 meters × 3 meters
= 480 cubic meters

Therefore, the swimming pool contains 480 cubic meters of water.
