Question 1 Surface Areas and Volumes - Exercise 13.5
A matchbox measures 4 cm x 2.5 cm x 1.5 cm.What will be the volume of a packet
containing 12 such boxes?
Answer:
Dimensions of a matchbox ( a cuboid) are l x b x h = 4 cm x 2.5 cm x 1.5 cm respectively
Formula to find the volume of matchbox = l x b x h = (4 x 2.5 x 1.5) = 15

"hello students welcome to lido qna video
session i am saf your math tutor
and question for today is a match box
measures
4 centimeter by 2.5 centimeter by 1.5
centimeter
what will be the volume of the packet
containing 12 such boxes
so data given to us is the length
breadth and height of the matchbox
that is length is
4 centimeter breadth of the matchbox
that is b
2.5 centimeter and height
that is h that is equal to 1.5
centimeter
now to find the volume we have
the volume of the cuboid
as matchbox is the cuboidal in shape we
should take
volume of the cuboid
length into breath into height
so 4 into 2.5 into 1.5
that is centimeter cube
this is the volume of one match box
now it is as that what will be the
volume of twelve such boxes
so volume of 12 such boxes
you just multiply 15 into 12
and you will get 15 into 12 that is 180
centimeter
cube that is your
required volume of 12 match boxes
therefore volume of 12 match boxes is
180 centimeter cube
