A $\mathrm{gulabjamun}$, contains sugar syrup up to about $30\mathrm{\%}$ of its volume. Find approximately how much syrup would be found in $45 \mathrm{gulabjamuns}$, each shaped like a cylinder with two hemispherical ends with length $\mathrm{}5\mathrm{}\mathrm{c}\mathrm{m}$ and diameter $\mathrm{}2.8\mathrm{}\mathrm{c}\mathrm{m}$ (see Fig.).

A pen stand made of wood is in the shape of a cuboid with four conical depressions to hold pens. The dimensions of the cuboid are $15 \mathrm{c}\mathrm{m}$ by $10 \mathrm{c}\mathrm{m}$ by $3.5 \mathrm{c}\mathrm{m}$. The radius of each of the depressions is $0.5 \mathrm{c}\mathrm{m}$ and the depth is $1.4 \mathrm{c}\mathrm{m}$. Find the volume of wood in the entire stand (see figure).
