2m 300mm = ____ cm

there are 100 cm in a metre

and 10 mm in 1 cm,
so ....

230cm

correct !

To convert meters (m) to centimeters (cm), you need to remember that 1 meter is equal to 100 centimeters.

So, let's start by converting 2 meters to centimeters:

2 meters x 100 centimeters/meter = 200 centimeters

Next, we need to convert 300 millimeters to centimeters. Since there are 10 millimeters in a centimeter, we can use the following conversion:

300 millimeters ÷ 10 millimeters/centimeter = 30 centimeters

Now, we can add the two measurements together to find the total in centimeters:

200 centimeters + 30 centimeters = 230 centimeters

Therefore, 2 meters 300 millimeters is equal to 230 centimeters.
