How many heating units are required to maintain temperature

A portable classroom is heated with small propane heating units with a capacity of 3 kW each. The portable classroom is occupied by 45 students, each dissipating 120 W, and is lighted by 10 light fixtures that dissipate 60W each. If the heat loss from the portable classroom is 15 kW, how many heating units are required to maintain the classroom at a temperature of 20 degrees celcius?
