Question

A crew of piano movers uses a 6.5-foot ramp to move a 990 lb Steinway concert grand up onto a stage that is 2.1 feet higher than the floor. How far away from the base of the stage should they set the end of the ramp so that the other end exactly reaches the stage?

Answer 1

distance = (6.5^2-2.1^2)^0.5

=6.15 foot

Answer 2

sqrt(6.5^2-2.1^2)=6.1514ft
