SA=2(wl+lh+hw)
cap s cap A is equal to 2 times open paren w l plus l h plus h w close paren
SA=lw+12w4h2+l2−−−−−−−√+12l4h2+w2−−−−−−−√
cap s cap A is equal to l w plus 1 half w square root of 4 h squared plus l squared end root plus 1 half l square root of 4 h squared plus w squared end root
SA=12ab+3(12lb)
cap s cap A is equal to 1 half A b plus 3 times open paren 1 half pounds close paren
SA=a2+2aa24+h2−−−−−−√
