Surface area of the cuboid =

Step-by-step explanation:

The given figure is in the shape of a cuboid with the given dimensions:

Length= 13.5 m

Width= 9 m

Height= 9 m

Surface area of the cuboid is:

               =  2((Length*Width)+(Width*Height)+(Height*Length))

Putting the values in the formula:

Area is :

The Surface area of the cuboid is

it would rotate about 180 degrees.
