Best Answer: Vacuuming burns ~0.024 calories/min/Lb. You burned 0.024*10min*108 = ~26 calories. Best of luck and good health! Impossible to answer since vacuuming is an intermittent activity, and there are too many other variables. Regardless 10 minutes of ANYTHING doesn't burn enough calories to matter. Unless of course you were to run 2 miles in 10 minutes, which would burn something like 200-250 calories. Your cardiovascular system isn't capable of transferring enough oxygen to do anything close to that, though, so its irrelevant.
Burning 3,500 calories through situps alone requires you to perform an impossible number of reps. If a 145-pound person performs situps at a moderate pace of 20 per minute, she burns about 4 calories per minute. To burn 3,500 calories, this person would need to perform situps for 875 minutes -- and perform an unattainable total of 17,500 situps.
