Question

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

Answer 1

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

Answer 2

Answer:

Answer: T.S.A = Explanation: The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube. C.S.A = Cube :-
