This net has been drawn on a centimetre grid. What is the surface area of this cuboid?

This cuboid is formed by 1cm unit cubes. What is the surface area of this shape?

No, you cannot work out the surface area of a cuboid like that.

Yes, that is one way you could work out the surface area of a cuboid.

Xavier says to find the surface area of a cuboid you can find the area of the front, side and base, add them together and double it. Do you agree?
