Dear student, We know that,Surface area of cube=6a2 where a =side of cube⇒6a2 =294⇒a2=2946⇒a2=49⇒a=7So, volume of cube=a3=73=343 Regards

Dear student,

W e k n o w t h a t, S u r f a c e a r e a o f c u b e = 6 a^{2} w h e r e a = s i d e o f c u b e \Rightarrow 6 a^{2} = 294 \Rightarrow a^{2} = \frac{294}{6} \Rightarrow a^{2} = 49 \Rightarrow a = 7 S o, v o l u m e o f c u b e = a^{3} = 7^{3} = 343
