The volume of a cube of side 1 cm is equal to .....m^3


(is the answer 0 because it is given significant figures??)

Answer 1

Answer:

Volume of cube= a^3

Here it is given in cm, so in meters it is 10^-2m

So by substituting the answer will be negligibly small.

So the answer becomes 0 according to significant figures rule.

Volume of a cube =(side)³

= ( 1 cm )³

= ( 1 × 10‐²m )³

= 1× 10‐⁶m
