Answer:
4425
Step-by-step explanation:
Volume of Metallic Parallelopiped = 16cm * 11cm * 10cm
Volume of Metallic Parallelopiped = 1760cm^3
Area of Disc = Pie*R*R
Diameter = 2*Radius
Radius of Circle = 2cm
Area of Disc = 2 * 2 * 22/7
Area of Disc = 12.5714 cm^2
Volume of Each Disc = Area * Thickness
Volume of Each Disc = 12.5714cm^2 * 0.2
Volume of Each Disc = 2.51428cm^3
Number of Discs = 1760/2.51428
Number of Discs = 4425
