How much water does it take to make a regulation size NHL hockey rink?

To determine the amount of water required to make a regulation size NHL hockey rink, we need to consider the dimensions of the rink and the required ice thickness.

A standard NHL hockey rink measures 200 feet long and 85 feet wide. The thickness of the ice varies but is typically around 1 inch or 2.54 centimeters.

To calculate the volume of water needed, we first need to convert the dimensions to a common unit. Let's convert feet to meters, and inches to meters:

200 feet = 60.96 meters
85 feet = 25.9 meters
1 inch = 0.0254 meters

Now let's calculate the volume of water required. We'll multiply the length, width, and thickness to get the volume in cubic meters:

Volume = Length x Width x Thickness
Volume = 60.96 meters x 25.9 meters x 0.0254 meters
Volume ≈ 40.007 cubic meters

So, it takes approximately 40 cubic meters of water to make a regulation size NHL hockey rink with a 1-inch ice thickness.

Keep in mind that this calculation is an estimate, as the ice thickness, temperature, and other factors may vary slightly.
