First we have to find the area of the hall 
Area of the hall =l×b
=16×12
=192m2
Area of the marble slab =8x6
=48cm2
{1 m2 =10,000 cm2}
(Convert m2 into cm2)
192m2=19,20,000 cm2
Therefore, how many slabs required=1920000÷48
=40000. 
Thus, 40000 tiles are needed to cover the floor.

Length of rectangular floor of room= 16 m = 1600 cm

breadth of rectangular floor= 12m = 1200 cm

∴Area of rectangular floor = length×  breadth =   1600× 1200 = 1920000 cm2

Area of rectangular tile = length×  breadth = 8× 6 = 48 cm2 9
Now number of tiles required to cover the floor = 19200/48 =40,000

number of tiles required =40,0000 tiles
