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.
