Question

The COST of the PAINTING the whole surface area of a cube at the RATE of 13 PAISE per centimetre square is Rs 343.98 the VOLUME of the cube is

$\underline{\Large{\underline{\textbf{\fbox{SOLUTION}}}}}\\\\The\ cost\ of\ painting\ the\ whole\ surface\ area\ of\ cube=Rs.\ 343.98\\\\\therefore\ Total\ surface\ area\ ={\frac{Rs.343.98}{13\ paise}$

$\\\\=\large{\bold{{\frac{\frac{343.98}{13}}{100}}}}}=\Large{\frac{343.98\times100}{13}}\\\\=\Large{\frac{34398}{13}}=2646\:cm^2\\\\\therefore6(edge)^2=2646\\\\\implies(edge)^2=441\\\\\implies edge=21\:cm\\\\Now,\: volume\: of\: cube\: \\\\=(edge)^3=(21)^3\\\\={9261\ cm^3$
