How many pieces of stone slabs, each 24cm long and 15cm broad will be required to lay a path of 18m long and 12m wide?

r-ruslan [8.4K]

Answer:

6,000

Step-by-step explanation:

The computation of the number of pieces of stone slabs required is shown below:

The Area of the path is

= 18 × 12

= 216 square meters

= 2160000 square meters

And, the area of each stone slab is

= 24 × 15

= 360 square centimeters

So, the number of pieces of stone slabs required is

= 2160000 ÷ 360

= 6,000
