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.
How many hours does it take to complete one song? ** 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.
How many hours did it take to complete the three songs? ** 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
