A hemisphere is cut out from one face of a cubical wooden block such that the diameter of the hemisphere is equal to the length of the cube. Determine the surface area of the remaining solid. 

A wooden article was made by scooping out a hemisphere from each end of a solid cylinder, as shown in the figure. If the height of the cylinder is $10 \mathrm{cm}$, and its base radius is of $3.5 \mathrm{cm}$, find the total surface area of the article. $\left(\text{Use}: \mathrm{\pi }=\frac{22}{7}\right)$

In the adjacent figure, the height of a solid cylinder is $10 \mathrm{cm}$ and diameter is $7 \mathrm{cm}$. Two equal conical holes of radius $3 \mathrm{cm}$ and height $4 \mathrm{cm}$ are cut off as shown the figure. Find the volume of the remaining solid.[Take $\mathrm{\pi }=\frac{22}{7}$]
