To find the total number of chairs in the building, we can break it down into steps:
- Determine the number of offices: There are 4 offices.
- Determine the number of people per office: There are 4 people in each office.
- Determine the number of chairs per person: Each person has 4 chairs.
Now, we can calculate the total number of chairs as follows:
-
Total people in the building: \[ \text{Total people} = \text{Number of offices} \times \text{Number of people per office} = 4 \times 4 = 16 \text{ people} \]
-
Total chairs in the building: \[ \text{Total chairs} = \text{Total people} \times \text{Number of chairs per person} = 16 \times 4 = 64 \text{ chairs} \]
Therefore, the total number of chairs in the building is 64.
