    @ helpmeplz311 bonus prob P=perimeter, P1=perimeter of P!, P2= perimeter of P2 P1=5+5+5+5=20 P2=10+10+4+4=28 B=bases, B!=area of base 1, B2=area of base 2 B1=5x5=25 B2=4x10=40 lateral surface area S= s(P!+P2)/2 lateral SA=6(20)(28)/2 =144 sq km ? is it? total SA=lateral SA + B1 +B2 = 144 +25 + 40 ? sq km is it? yes or no?
