Hi Priyanshu37 !
______________________________________________________________
Surface area of Cube = 98/3 m²
Surface area of cube = 6l²(if the side of cube is l)
ATQ
6l² =98/3
18l² =98
l² =98/18
l² = 5.44
√ l²=√5.44
l = 2.33 m
____________________________________________________________
So volume of cube = l³
= (2.33)³
=12.68 m³

let the side of the cube be "a"
surface area = 6a²
6a² = 98/3
a² = 98/3/6
a² = 5.45
a= √5.45
a= 2.34
volume = a³
=(2.34)³
=12.68
hope it helps!!!!
