Calculate the amount of work involved in lifting ONE box without the use of a simple machine.

• 15 / 3 = 5 Joules

• 15 * 3 = 45 Joules

• 40 / 15 = 2.67 Joules

• (15 / 3 )* 40 = 200 Joules

Calculate the amount of work involved in lifting ALL of the boxes without the use of a simple machine.

• 15 * 40 = 600 Joules

• (15 / 3 ) * 40 = 200 Joules

• (15*3) * 40= 1800 Joules

• None of the above
