Answer 1

Answer:

if it is helpful mark me as brainliest

Step-by-step explanation:

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.
