Volume of a cylinder = the area of the base x height of the cylinder
Area of base =
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
r^2
A = 6^2(
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
)
A = 36
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
V = 36
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
x 12
V = 432
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
5 cylinders = 5V
5V = 5 x (432
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
)
5V = 2160

Final answer: Alex needs to buy 2160
