#3292.8J#

Explanation:

if we take the ground level as the zeroth level of gravitational potential energy, then the potential energy that get stored in the object when you lift it #21m# is the work you should do.

#W= mgh#
where W represents the work you should do..

#W= 16kg* 9.8ms^"-2" *21m#

#W= 3292.8 J#
