Crates and weights

Puzzle:

I have ten boxes which I want to pack into crates. Each crate can carry a maximum of 25 kg.

15 kg, 13kg, 11 kg, 10 kg, 9 kg, 8 kg, 4 kg, 2 kg, 2kg, 1 kg

How can I pack the boxes into the crates?

volume of PIZZA

Puzzle: 

 If you had a pizza with crust thickness 'a' and radius 'z', what's the volume of the pizza?

ANSWER:

Volume = pizza

Your volume will be the area of the pizza times the height.

Since Area = pi*r^2 and radius = z, the area = pizz

Multiplying this times the height (a) gives you a product we all know and love:

Volume = pizza!
