There is a thin metal plate of length and breadth 2M mm and 2K mm respectively. Its thickness is 1 mm. If ‘N′ number of plates are placed one on top of the other, what is the object formed and what is its volume in mm3?
Thickness of 1 plate =1 mm
Total thickness of N plates put together =N mm
The object formed has now three dimensions - Length, breadth and thickness.
The area of one plate =Length×Breadth
The object formed when thin plates are stacked together is nothing but a cuboid. This can be visualised as shown below.
Volume=Plate Area×Total Thickness
