First, you calculate the capacity of each container. So, we find the volume of the cylindrical container. The formula would be:
V = pi*r²*h
V = (3.14)*(4/2)²*8
V = 100.48 cubic cm
To make 2000 cm³, we divide this by the capacity of each container:
Number of containers = 2000/100.48
Number of containers = 19.9
Thus, the minimum number of containers is 20.
