Question: A singer is planning on releasing 3 songs in a month. If he worked on one song for 10 hours a day, and each song took 10 days to be completed, calculate the total number of hours he took to complete the 3 songs. Is final answer 300?
Answer: If he worked on a song for 10 hours a day, the total number of hours he takes to complete one song is 10*10 = <<10*10=100>>100 hours.
If one song took 100 hours to complete, the total number of hours the three songs took to be completed is 3*100 = <<3*100=300>>300 hours
#### 300
