A toy in the shape of a hemisphere of radius $7 c m$ is surmounted by a cone of slant height $25 c m$ . The toy is placed in a cylindrical box of radius $70 c m$ and height $1 m$ , which is to be packed and dispatched. Find how many such toys can be accommodated in the box. Assume packaging occupies a volume of $\frac{11}{3} (c m)^{3}$ for each toy and all toys need to be packed.(Take $π = \frac{22}{7}$ )
