Question

Please help me!!!!!!

Answer 1

i think 650

Answer 2

Thank you

Answer 3

ur welcome

Answer 4

@satellite73, @Sufiyancs what do u guys think?

Answer 5

I just need to understand, how will i get this ?

Answer 6

surface are of cuboid = 2(l*b)+2(bh)+2(l*h)
so just divide the figure into 2 parts

Answer 7

therefore, surface area of 1 cuboid = 2(10*5)+2(5*5)+2(10*5)

Answer 8

that is equal to 250 and then surface area of 2 cuboid = 2(20*5)+2(5*5)+2(20*5)=450

Answer 9

therefore 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 700-50=650

Answer 10

if u dont get the last part divide the figure into 3 parts

Answer 11

Thank you so much guys for helping :) thanks alot @Sufiyancs !!! you guys are truly awesome!!!!!!

Answer 12

ammm 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

Answer 13

Oh ok :) thank you so much!

Answer 14

i have divided it into 3 parts as i said before

Answer 15

anytime
