since three cubes of volume 216 m3 are joined together so we get the cuboid of length

=(6+6+6)=18m

Breadth of the resulting cuboid is 18m

Height of the resulting cuboid is 18m

surface area of the resulting solid or cuboid is

=2(lb + bh + lh)

=2{(18 x 6) + (6 x 6) + (6 X 18)}

=2 {108+36+108}

=2 X 252

=504m^2

surface area of the resulting solid is 504m^2
