We derive the formula for the volume of a cuboid asl x bx h.
Voiume of a cuboid = Length x Breadth x Height
= ixbxh

The cuboid is made up of 1-m cubes. Find the voiume of the cuboid.

Solution
Volume of cuboid = Length x Breadth x Height
=6x4x5
= 120 m^

The volume of the cuboid is 120 m^.

The cake, in the shape of a cuboid, is 10 cm long, 6 cm wide and 7 cm high
Find the volume of the cake.
Solution
Voiume of cake = Length x Breadth x Height
= 10 X 6 X 7
7 cm
= 420 cm^
10 cm
The volume of the cake is 420 cm^.
6 cm

Calculate the volume of this cuboid.
Remember to write the
Solution
2 cm units. The dimensions are
V = lhh
in cm, so the volume is in
=6X3X2
cm*
= 36 cm^
6 cm
The volume of the cuboid is 36 cm^
