As we know,
Whole Surface area of cube
= 6* (side)^2 .
Here,
Cost of painting whole Surface area = Rs 343.98
And, Cost of painting per sq.cm. = 13 paise
= Rs 0.13
So, Whole surface area = 343.98/0.13
= 2646 sq.cm i.e. 6*(side)^2
=> side ^2 = 2646/6 = 441.
=> side = 21 cm.
Now, Volume of cube = side^3 = 21^3
= 9261 cm^3.
