A number having 7 at its ones place will have 3 at the ones place of its cube.

Answer:

**True.**

When a number with a unit digit of 7 is cubed, it will have 3 (7^{3} = 343) at the unit's location.

Let us take the number having 7 at its ones place i.e. 37 and

\begin{aligned} &\text { Its square } 37^{3}=50,653\\ &\text { Another number is } 27^{3}=19,683 \end{aligned}
