First you find the area of the front face 1/2bh or in you case 10x12=120 1/2 of 120 is 60 next you multiply 60 by 20 to get 1,200 for the voulume
we know that
if JKLM is a rectangle
then
diagonals
MK=JL
so
MK=2*MN------> MK=2*25 ft------> MK=50 ft
JL=MK----> JL=50 ft
therefore
the answer is
JL is 50 ft
