How many 100-centimetre cubed bottles are needed to hold nine liters of liquid?

Our first step here is to convert nine liters into centimetres cubed. What we should know that one liter is equivalent to 1000 centimetres cubed. Therefore, we need to multiply the number of liters by 1000. Nine multiplied by 1000 is equal to 9000. This means that nine liters is equal to 9000 centimetres cubed.

We were told that each bottle holds 100 centimetres cubed. We need to work out how many of these are required to hold 9000 centimetres cubed. The number of bottles can be calculated by dividing 9000 by 100. 9000 divided by 100 is equivalent to 90 divided by one. This is equal to 90.

Therefore, 90 100-centimetre cubed bottles are needed to hold nine liters of liquid.
