Question

what is the formula of CSA and TSA of cube , cuboid andother important figures

Answer 1

$TSA\:of\:cylinder=2\pi rh +2\pi r^{2}\\</p><p>TSA\:of\:hemisphere=3\pi r^{2}\\</p><p>TSA\:of\:sphere=4\pi r^{2}\\</p><p>TSA\:of\:cone=\pi r(r+l)\:\:or \:\:\pi rl + \pi r^{2}\\</p><p>TSA\:of\:cube=6s^{2}\\</p><p>TSA\:of\:cuboid=2(lb+lh+bh)\\\\</p><p></p><p>CSA\:of\:cylinder=2\pi rh\\</p><p>CSA\:of\:hemisphere=2\pi r^{2}\\</p><p>CSA\:of\:sphere=4\pi r^{2} (same\:as\:TSA\:of\:sphere)\\</p><p>CSA\:of\:cone=\pi rl\\</p><p>CSA\:of\:cube=4s^{2}\\</p><p>CSA\:of\:cuboid=2(lb+bh)$
