If two cubes each of side 6 cm are joined face to face, then find the volume of the resulting cuboid.

Answer»

Side of two equal cubes = 6 cm

When we join, two cubes face to face formed a cuboid.

Dimensions of a cuboid are: 

Length = 6 cm + 6 cm = 12 cm 

Breadth = 6 cm 

Height = 6 cm 

Therefore, volume of cuboid = lbh 

= 12 x 6 x 6 

= 432 cm3
