A rather confusing questions.
Do you want the volume to increase by 1/4
or each side to increase by 1/4
The statement "What will be the size of all its size in cm3?? " makes no sense.
I will assume your volume is to increase by 1/4
Old volume = 4^3 = 64
increase that by 1/4 or (5/4)(64) = 80
so each side is x
x^3 = 80
new side = cuberoot(80)
you do the button-pushing
