How many cubic centimeters of liquid can be poured into a rectangular baking pan that is 45 cm by 20 cm?

You need to know the depth (or height) of the baking pan to calculate the volume in cubic centimeters.

Here's why:

* Volume is the amount of space a three-dimensional object takes up.

* For a rectangular shape, volume is calculated by: Length x Width x Height

To solve the problem, you need to know the height of the pan.

Let's say the pan is 5 cm deep. Here's how you'd calculate the volume:

1. Length x Width x Height = Volume

2. 45 cm x 20 cm x 5 cm = 4500 cubic centimeters

So, if the pan is 5 cm deep, you could pour 4500 cubic centimeters of liquid into it.
