प्रश्न
If two cubes each of side 6 cm are joined face to face, then find the volume of the resulting cuboid.
उत्तर
We have,
Side of each cube (a) = 6 cm
We need to find the volume of resulting cuboid
Hence, dimensions of the resulting cuboid are,
Length (l) = 2a
= 2 × 6
= 12 cm
Breadth (b) = a
= 6 cm
Height (h) = a
= 6 cm
Hence, volume of the resulting cuboid,
`V = lbh`
`=12 xx 6xx 6`
`=432 cm^3`
Hence, volume of the resulting cuboid is 432 cm3.
