Answer 1

Answer:

For covering  $1$ unit area of the entire playground, the amount of sand required is equal to volume of $3$ buckets of sand.

Step-by-step explanation:

Given -

$\frac{1}{3}$ volume of sand in bucket is able to cover $\frac{1}{9}$ area of the entire playground

Thus,

For covering  $\frac{1}{9}$ unit area of the entire playground, the amount of sand required is equal to  $\frac{1}{3}$  of the total volume of sand in bucket

For covering  $1$ unit area of the entire playground, the amount of sand required is equal to

$\frac{\frac{1}{3} }{\frac{1}{9} } \\\\\frac{1}{3} * \frac{9}{1} \\\frac{9}{3}\\= 3$

For covering  $1$ unit area of the entire playground, the amount of sand required is equal to volume of $3$ buckets of sand.
