the surface area is the sum of the areas of all the sides ... the two ends are W*H, two of the faces are L*H and the other two faces are L*W ... so S.A.=2(W*H)+2(L*H)+2(L*W) or 2((W*H)+(L*H)+(L*W))

1.) S.A.=2((2.9*4.7)+(3.5*4.7)+(3.5*2.9}) ... S.A.=80.46 sq m

2.) S.A.=2((15.1*4.5)+(6.5*4.5)+(6.5*15.1)) ... S.A.=390.7 sq m
