Jessica has one cube with a side length of $1,$ and another cube with a side length of $1.$ She then glues the two cubes together, to form one single solid. What is the smallest possible surface area of the single solid?

*Jessica has one cube with a side length of $1,$ and another cube with a side length of $1.$ She then glues the two cubes together, to form one single solid. What is the smallest possible surface area of the single solid?*

Each cube will have a surface area of 6 square units, for a total of 12 square units.

When Jessica sticks them together, she lost two surfaces because they're on the inside now.

So the remaining surface area is **10 square units**.
