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*[tex] 10^{6} [/tex] (≈ symbol means it's approximate)
SA≈1,620,000
Thus, your answer, D.
