1. The problem statement, all variables and given/known data Estimate the number of Ping - Pong balls that would fit into a typical-size room (without being crushed). In your solution state the quantities you measure or estimate and the values you take for them. (Assume 25% of the space cannot be filled due to spherical packing.) (a) Find the volume of the room (in m^3) (b) Find the volume of a ball (in cm^3) (c) Find the number of balls (order of magnitude only) (balls) 2. Relevant equations 75% of 1000m^3 = 750m^3 750m^3(1 000 000 cm^3/1m^3) 3. The attempt at a solution (a)I said that an average room had 1000m^3 It said "Your response differs from the correct answer by orders of magnitude." (b) I said the volume of a ball had 100cm^3 It said "Your response differs from the correct answer by more than 100%." (c) I said the number of balls equaled 7.5e6 It said "Your response differs from the correct answer by more than 100%." Any help would be greatly appreciated!
