Answer: (C) a portable mp3 player
Step-by-step explanation:
A portable mp3 player is a device which we can carry around and listen to music anytime. A mp3 player has a volume as it can be a cuboidal structure.
A MP3 player has an associated length, breadth and a height. So using this combination we can find the volume of the mp3 player.
Here in the question we are given the volume is 75 cm³.
If we consider the length and the breadth to be around 5 cm each and the height to be around 3 cm.
Then the Volume (V) = L x B x H
= 5 x 5 x 3
= 75 cm³.
Therefore, it is most likely to be a portable mp3 player
