To calculate the volume of water the tank holds, we use the formula for the volume of a rectangular prism:

$\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}$

In this case:

• Length = 19 inches
• Width = 10.5 inches
• Height (depth of the water) = 11 inches

Now, substitute these values into the formula:

$\text{Volume} = 19 \times 10.5 \times 11 = 2194.5 \text{ cubic inches}$

So, the tank holds 2,194.5 cubic inches of water.

Here are 5 related questions you might find helpful:

1. How can you convert cubic inches to gallons?
2. What happens to the volume if the water depth is doubled?
3. How would the volume change if the dimensions of the tank were scaled up by 10%?
4. How can you calculate the weight of the water in the tank?
5. What would be the volume if the tank were filled to a different height?

Tip: When working with rectangular prisms, always multiply the three dimensions (length, width, height) to find the volume!
