A plant 73cm tall.how many more centimetres does it have to grow before it is 1 metre tall?

well, 1 meter is 100 cm.

So, how much is still needed?

To find out how many more centimeters the plant has to grow before it reaches 1 meter (100 centimeters) in height, we can subtract its current height of 73 centimeters from 100 centimeters.

100 cm - 73 cm = 27 cm

Therefore, the plant has to grow 27 more centimeters to reach a height of 1 meter.
