Hello Dear User__________

Here is Your Answer...!!

____________________

Step by step solution:

Given surface area is 150 $\ m^2$

Let side be a m

We know that surface area =6$\ a^2$

So 6$\ a^2$ = 150

a = 5 m

Now volume = $\ a^3$

volume of cube  having side 5m = $\ 5^3$ = 125$\ m^3.$

So option A. is correct.
