Verified Answer :

Simple...if this is a right rectangular prism..then you already know the formula for surface area...

Surface Area: 2(wl+hl+hw)

plug in what you know...

l=729

w=413

h=447

2((413)(729)+(447)(729)+(447)(413))

Surface Area≈1.62*\(10^{6}\)  (≈ symbol means it's approximate)

SA≈1,620,000

Thus, your answer, D.
