INTRODUCTION
Each solid below is made up of centimetre cubes. Work out their
respective volumes.
VOLUME =
(Because it is made up of 12 cubes)

VOLUME OF A CUBOID = Length x Width x Height
EXAMPLES
Find the volume of the cuboids below in cm3 :
1)

3)
Volume = l x w x h
Volume = l x w x h
Volume = l x w x h
Volume = 12cmx 6cm x 9cm Volume = 5.2cmx 5.2cmx5.2cm Volume = 7.8mx3.5mx 4.7m
Volume = 648cm 3
Volume = 140.6cm3 (1d.p.) Volume = 128.31m 3
