प्रश्न
The volume of a cuboid is 7.68 m3. If its length = 3.2 m and height = 1.0 m; find its breadth.
उत्तर
The volume of a cuboid = 7.68 m3
Length of a cuboid = 3.2 m
Height of a cuboid = 10m
We know
Length x Breadth x Height = Volume of a cuboid
3.2 x Breadth x 1.0 = 7.68
⇒ Breadth = `7.68/(3.2 xx 1.0)`
⇒ Breadth = `7.68/3.2`
⇒ Breadth = 2.4 m
