Hilda The Builder Puzzle - Solution
The Puzzle:
Hilda made a house from building blocks and it looked like this from the top and two sides.
How many bricks did Hilda use altogether?
Our Solution:
While I make no claims to be an expert on perspective drawing, the diagram shows the building made of 22 blocks.
In fact it is possible to add up to 3 other blocks without affecting the three views.
