Question

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

Answer 1

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
