____________________________________________________________

Two cubes of edge 10 m are joined forming a cuboid

The l, b, h of the resulting cuboid will be:

Length of resulting cuboid = 20m
Breadth of resulting cuboid = 10m
Height of resulting cuboid = 10m

Surface area of cuboid =

2 ( lb + bh + hl ) m²

2 (20*10 + 10*10 + 10*20 ) m²

2 ( 200 + 100 + 200 ) m²

2 (500) m²

1000 m²

So the surface area of the resulting cuboid will be 1000m²
