Car Wash Sponges!

In order to wash the cars you need sponges! Sponges come in all different shapes, sizes and colors. The corners of square sponges would work best when cleaning small, tight areas of the car (like cleaning the tires). You could also find circle, rectangular, and oval shaped sponges.


You would need to make sure you have enough sponges to wash all the cars. Make sure to buy in bulk!

If 25 cars came to your car wash, can you estimate how many sponges you might need?
