Question

Three cubes are joined together having measures 6cm . Find the surface area of new figure

Answer 1

Answer:

504 cm²

Step-by-step explanation:

Length of resulting cuboid :- 6+6+6 = 18 cm

Breadth and height will remain same

So,

Breadth = 6 cm

Height = 6 cm

Surface area of resulting cuboid :-

= 2(lb+bh+hl)

= 2(18×6+6×6+6×18)

= 2(108+36+108)

= 2(252)

= 504 cm².
