The side view of the seven cubes: columns 2 then 3. Then the cubes are drawn turned a quarter turn, with a curved arrow over them, so the old right side faces front. The new front view appears: 2 then 3, the old side view. The last step asks about a building whose front view is 3, 2, 2.

The big idea
Turning a building is like walking round it: the side you bring to the front sets the view.
For exampleCheck a drawing with real cubes: build the building, set the drawing beside it, and turn the cubes until each view faces you.
Easy to get wrongA quarter turn is not a flip. It brings a side to the front; only a half turn brings the back round.
Key word
- quarter turn
- turning an object a quarter of the way round, so a side that faced right now faces you
