Jeff stacked 5 boxes in a storage room. Each box is 3.75 feet high.
The first box was placed on a platform so that the bottom of the box was a foot above the floor of the storage room.
The boxes are stacked one on top of the other with no space between the boxes.
The top of the last box is.. foot from the ceiling of the storage room.
What is the height of the storage room from the floor to the ceiling?
