Question

Can anyone help me find the surface area of this shape?

Answer 1

To find the surface area of a cuboid you have to find the areas of all the faces and then add them all up together.
2*2=4
4+4=8 (adding this because there's 2 of these same faces)
9*2=18
18*4=72 (because there's 4 of these same faces)

8+72=80

So the answer is 80cm
