Well, let's see. We have a unit "ft-lb", we have a unit "ft", we have a unit "lb" ... you know, I bet if you multiply the "lb" number by the "ft" number it will give you the "ft-lb" number.
(The fancy word for this sort of reasoning is "dimensional analysis", and you'd be surprised how far it will get you in solving problems in college chemistry and physics courses, even if you don't have the faintest clue what you're doing otherwise.)
3000
Its far closer to 6ft. They range in height but nothing remotely near 60ft unless we're including the building then its a different story.
The work done is calculated as the force applied multiplied by the distance moved in the direction of the force. In this case, the work done is 30,000 ft-lb (500 lb × 60 ft).
The diagonals of 60ft by 40ft are 72.11 feet.
60ft
1yd = 3ft 20yd x 3ft/yd = 60ft 60ft + 1ft = 61ft
20
they are 60ft long
60' = 1828.8 cm
60ft = 0.0183km
18.3 meters.
60ft = 0.0183km
