A room measures 3 meters wide, 4 meters long, and 2.5 meters high. 1. What is the surface area of the room in square meters (including the ceiling and floor)?

2. If a certain paint covers 25 square meters per gallon, how many gallons will it take to
paint the walls and ceiling, but not the floor?

3. Describe three objects that belong to the microscopic scale and three objects that belong to the macroscopic scale.
