Q. Your ceiling is

\mathbf{2 1 0}

centimetres high, You want the tree to have

\mathbf{3 0}

centimetres of space with the ceiling. How tall must the tree be? (in centimetres)

Understand the problem: Understand the problem. $\newline$ We need to find the maximum height of a tree that can fit under a $210$ -centimetre high ceiling while maintaining a $30$ -centimetre gap between the top of the tree and the ceiling.
Subtract required space: Subtract the required space from the ceiling height to find the maximum height of the tree. $210$ centimetres (ceiling height) $- 30$ centimetres (required space) $= 180$ centimetres (maximum tree height).
