this is find the surfae area
with some logic and simplifiaction we get
SA=2(LW+LH+WH)
lw means legnth times width
lh means legnth times height
wh=width times height
L=14
W=12
H=6
(It doesn't matter which is which when working with this shape)
SA=2(1412+146126)
SA=2(168+84+72)
SA=2(324)
SA=648
answer is 648 in^2
