Puzzle 609 


Unluckily, last week I lost my measuring tape. It was unlucky as I had to measure Billy's toy box.

Luckily though I could remember that the top had an area of 720 square inches, the side was 800 square inches, and the end was 360 square inches.

What were the true dimensions of the toy box?

Puzzle 612 


I recently gave a new carriage clock to my friend for a very special birthday.

However, as usual with my presents, it was quite useless as it loses 6 minutes every hour.

I set it using my own accurate clock at midnight, and the clock now shows 10:12am.

I know that it stopped 2 hours ago, so what is the correct time now?
