Best ResponseYou've already chosen the best response.1surface are of cuboid = 2(l*b)+2(bh)+2(l*h) so just divide the figure into 2 parts

Best ResponseYou've already chosen the best response.1therefore, surface area of 1 cuboid = 2(10*5)+2(5*5)+2(10*5)

Best ResponseYou've already chosen the best response.1that is equal to 250 and then surface area of 2 cuboid = 2(20*5)+2(5*5)+2(20*5)=450

Best ResponseYou've already chosen the best response.1therefore total surface area is 250+450=700 But as i have counted one line twice just the one next to 15 so the actual answer is 70050=650

Best ResponseYou've already chosen the best response.1ammm sorry its 750... this is how we do it.. 2(5*5)+2(5*5)+2(5*5)=150 2(10*5)+2(5*5)+2(10*5)=250 2(15*5)+2(5*5)+2(15*5)=350 Total surface area= 150+250+350 = 750cm Square
