Two cubes of edge lengths $4\text{ cm}$ and $6\text{ cm}$ are joined by aligning one face of the smaller cube to a face of the larger cube. Determine the total surface area of the resulting solid.

A triangular prism has an equilateral triangle cross section of side $8\text{ cm}$ and length $12\text{ cm}$. A half-cylinder of radius $4\text{ cm}$ and height $12\text{ cm}$ is attached along one rectangular face of the prism. Determine the total surface area of the composite solid.

A cube of edge length $10\text{ cm}$ has a square-based pyramid attached to its top face. The pyramid has base side $10\text{ cm}$ and height $6\text{ cm}$. Find the total surface area of the composite solid.

A solid is formed by attaching a hemisphere of radius $3\text{ cm}$ to one end of a right circular cylinder of radius $3\text{ cm}$ and height $8\text{ cm}$. Find the total surface area of the composite solid.

A right circular cone of radius $3\text{ cm}$ and height $4\text{ cm}$ is joined by its base to one end of a cylinder of the same radius and height $3\text{ cm}$. Another identical cone is joined by its base to the other end of the cylinder. Calculate the total surface area of the resulting solid, giving your answer in terms of $\pi$.

A cylinder of radius $5\text{ cm}$ and height $15\text{ cm}$ has a square prism hole of cross section $6\text{ cm}\times 6\text{ cm}$ drilled completely through its axis. Calculate the total surface area of the hollow solid.
