The rim (circular boundary) of a hemispherical bowl is $88\text{cm}$. Assuming the bowl is completely filled, how many people can be served if the content is distributed into hemispherical glasses, where each glass has a top diameter of $7\text{cm}$? (Take $\pi =\frac{22}{7}$)

A hemispherical bowl is $88\text{cm}$ round the brim. Assuming it to be full, how many persons may be served from it in hemispherical glasses, $7\text{cm}$ in diameter at the top? (Where $\pi =\frac{22}{7}$)

The volume of a cube is four times the volume of a cuboid. If the sides of the cuboid are $32\text{cm}$, $8\text{cm}$ and $4\text{cm}$, then find the ratio of the total surface area of the cube to that of the cuboid.
