1 The gym is 9 meters long and 6 meters wide. How many square bricks does it take to cover the whole floor with square bricks with a side length of 30dm? How much is the 8 yuan for each such square brick? Both questions are wrong!

A square brick with a side length of 30dm is a square brick with a side length of 3 meters. Is there such a big brick? It's 30cm, right?

9 m = 900 cm =30x30

6 meters =600cm=20x30

30x20=600

If you cover the whole ground with square bricks with a side length of 30cm, you need 600 square bricks.

8x600=4800

* * * 4800 yuan.

1 A square red paper with a side length of 6cm cannot be made into a triangular red flag with a bottom of 30cm and a height of 20cm.

If you make a triangular red flag with a base of 3cm and a height of 2cm, you can make 12 faces.
