VOLUME:
The space occupied by an object solid body
is called the volume of the particular object solid body volume is always
measured in cubic unit.
Given:
Dimension of matchbox =4cm×2.5cm×1.5cm
l=4cm,b=2.5cm & h=1.5cm
Volume of cuboid =(l×b×h)
Volume of one matchbox = Volume of cuboid
Volume of one matchbox =4×2.5×1.5=15cm
3
Volume of a packet containing 12 such boxes = 12× volume of one match box
(12×15)cm
3
=180cm
