Best ResponseYou've already chosen the best response.0each panel is 42 square meters there are 6 of them 42*6 = 252 square meters so far, the total surface area is 93.53+252 = 345.53

Best ResponseYou've already chosen the best response.0there are 6 such triangles 6*45 = 270 so 270 square meters is the surface area of the pyramid up top (ignoring the bottom face)

Best ResponseYou've already chosen the best response.0in total, the composite 3D figure has 93.53+252+270 = 615.53 square meters of surface area
