Answer 1

The number of marbles is 4032.

Step-by-step explanation:

The dimension of marble slabs is 40 cm× 20 cm.

The area of marble slab is $A=l\times b$

$A_m=40\times 20$

$A_m=800\ cm$

The square Park of side 18 m to a width of 2 cm.

Convert 18 m into cm,

$1\ m = 100\ cm$

$18\ m = 1800\ cm$

The actual side of square is $s=1800-2-2=1796\ cm$

The area of the square is $A=s^2$

$A_s=1796^2$

$A_s=3225616$

The number of marbles is given by,

$n=\frac{A_s}{A_m}$

$n=\frac{3225616}{800}$

$n=4032.02$

Therefore, the number of marbles is 4032.
