There is a thin metal plate having length, breadth, and thickness as 2M mm, 2K mm and 1 mm, respectively. If ‘N’ plates are placed one on top of the other, then what is the object formed. Also, find its volume in $m m^{3}$ ?

Solution

Thickness of 1 plate = 1 mm.
Total thickness of N plates put together = N mm

Now, the object formed has 3 dimensions- length, breadth, and thickness.

The area of one plate
$= Length \times Breadth$
$= 2 M \times 2 K$
$= 4 M K m m^{2}$

The object formed when thin plates are stacked is nothing but a cuboid. This can be visualised as shown below.

$Volume = Area \times Thickness$
$= 4 M K \times N$
$= 4 M K N m m^{3}$
