Question

Three cubes of each side 4cm are joining end to end. Find the surface area of resulting cuboid.

Answer 1

lenght of cuboid - 12 cm , breadth- 4cm ,height- 4cm then , surface area of cuboid - 2 ( lxb plus bxh plus hxl ) so, surface area of cuboid-- 2 ( 12x 4 plus 4x4 plus 4x12 ) -- 2 ( 48 plus 16 plus 48 ) -- 2 ( 112 ) -- 224 sq cm

Answer 2

Answer:

Step-by-step explanation:

lenght of cuboid - 12 cm ,

breadth- 4cm ,

height- 4cm then ,

surface area of cuboid - 2 ( lxb + bxh +hxl )

so,

surface area of cuboid-- 2 ( 12x 4 +4x4 +4x12 )- 2 ( 48 + 16 +48 ) -- 2 ( 112 ) -- 224 sq
