60+18=78

78*3=234

Answer 2

Calculating the Total Number of Radiators Needed for the Building

To calculate the total number of radiators needed for the building, we can follow these steps:

1. Calculate the Total Number of Apartments in the Building: - Since there are 3 apartments on each of the 16 floors, we can calculate the total number of apartments by multiplying the number of floors by the number of apartments on each floor.

2. Calculate the Total Number of Radiators for Each Type of Apartment: - We know the number of radiators required for each type of apartment: 3 for a one-bedroom, 5 for a two-bedroom, and 7 for a three-bedroom.

3. Multiply the Number of Radiators by the Total Number of Each Apartment Type: - After calculating the total number of each type of apartment, we can then multiply the number of radiators required for each type by the total number of each type of apartment.

4. Add the Total Number of Radiators for Each Apartment Type: - Finally, we can add the total number of radiators for each type of apartment to find the overall total number of radiators needed for the building.

Let's proceed with the calculations.

Calculation

1. Total Number of Apartments: - Total number of floors: 16 - Apartments on each floor: 3 - Total number of apartments = 16 floors * 3 apartments/floor

2. Total Number of Radiators for Each Type of Apartment: - One-bedroom: 3 radiators - Two-bedroom: 5 radiators - Three-bedroom: 7 radiators

3. Calculation: - Total number of one-bedroom apartments = 16 floors * 1/3 * 3 apartments/floor - Total number of two-bedroom apartments = 16 floors * 1/3 * 3 apartments/floor - Total number of three-bedroom apartments = 16 floors * 1/3 * 3 apartments/floor

4. Total Number of Radiators Needed: - Total number of radiators = (Total number of one-bedroom apartments * 3) + (Total number of two-bedroom apartments * 5) + (Total number of three-bedroom apartments * 7)

Result

The total number of radiators needed for the building can be calculated using the above steps.
