TSA of a cube is 6a^2 where 'a' is the side of the cube.
TSA of a cuboid is 2(lb+bh+hl) where 'l' is the length, 'b' is the breadth, 'h' is the height of the cuboid.
TSA of a cone is πr(l+r) where 'r' is the radius of the cone and 'l' is the slant height of the cone.
TSA of a cylinder is 4πr(h+r) where 'h' is the height and 'r' is the radius of the cylinder.
TSA of a sphere is 4πr^2 where 'r' is the radius of the sphere.
TSA of a hemisphere is 3πr^2 where 'r' is the radius of the hemisphere.
TSA of a frustum of a cone is πl(R+r)+π(R+r) where 'l' is the slant height of the frustum, 'R' is the big radius of the frustum and 'r' is the small radius of the frustum of cone.
