Answer:

It is not a perfect cube.

The smallest number by which 243 must be multiplied to be a perfect cube is

3

how we found it?

243 = 3×3×3×3×3

= (3×3×3)×3×3

= 3³×3×3

to make a perfect cube we have to multiply 3 or divide 9 (3×3). But here we have to find answer with multiplication, so answer will be 3.

243×3 = 729

It is a perfect cube.

729 = 3×3×3×3×3×3

= 3³×3³

= 9³

hope it helps.
