Question

7. Find the volume of: (a) a cuboid of L = 5 m, B = 4.5 m, H = 2 m (c) a cuboid of L = 30 cm, B = 25 cm, H = 10.5 cm = (b) a cube of edge = 6 m (d) a cube of edge = 11 cm -​

Answer 1

Answer:

Cuboid is a solid box whose every surface is a rectangle of same area or different areas.

Since volume involves 3 sides it is measured in cubic units.Units of VolumeVolume of a cuboid = (length × breadth × height) cubic units.= (l × b × h) cubic units. (Since area = ℓ × b)Volume of a cuboid = area of one surface × height cubic unitsLet us look at the given cuboid.The length of the cuboid = 5 cmThe breadth of the cuboid = 3 cmThe height of cuboid (thickness) = 2 cmThe number of 1 cm cubes in the given cuboid = 30 cubes = 5 × 3 × 2We find that volume of the given cuboid with length 5 cm, breadth 3 cm and height 2 cm is 30 cu cm.
