Find the surface area 729 height, 413 length, 447 width, A. 1 589 B. 9534 C. 811,551 D. 1,623,102

Surface area=2 (legnth times width) + 2 (legnth times height) + 2 (height times width)

this is because there are 6 faces and 2 are idencical, assuming this is a regular rectangular prism.

subsitute

SA=2 (413 times 477) + 2 (413 times 729) + 2 (729 times 447) = 2 (197001) + 2 (301077) + 2 (325863) = 394002+602154+651726=1,666,842

the surface area is closest to D
