it is 2100 Joules

Explanation:

Gravitational potential energy, GPE, is given by the formula:
$G P E = m g h$ $GPE=mgh$

where
$m = mass = 70 k g$ $m="mass"=70kg$
$g = acceleration due to gravity = 10m/s/s$ $g= "acceleration due to gravity"="10m/s/s"$
$h = height above earth's surface = 3 m$ $h = "height above earth's surface" = 3m$

So $m g h = 70 \times 10 \times 3 = 2100 Joules$ $mgh=70times 10times3=2100 " Joules"$
