Question

a 70 kg student stands on top of a 5.0 m platform diving board . how much gravitational potential energy does the student have?
how much work did it take for the student to travel from the ground to the top of the platform diving board? ​
P.E. = m g h

work = P.E.
Pe=(70)(9.8)(5.0)
Pe=3430 J
Is this right
yes ... but the number of significant figures is iffy
