 Hello and how are you all today? Let us discuss this question. It says a matchbox measure is 4 cm x 2.5 cm x 1.5 cm. What will be the volume of a packet containing 12 such boxes? So before proceeding on with the solution, we should be well versed with the formula that is volume of a cuboid. It is equal to length x breadth x height. And the knowledge of this formula is the key idea for this question. Here the length, breadth and height one box is given to us as 4 cm, 2.5 cm and 1.5 cm respectively. First of all we need to find out volume of one box that is length x breadth x height that is 4 x 2.5 x 1.5 cm further equal to 15 cm cube. And then we need to find out volume of 12 such boxes that will be volume of one box into 12 that is further equal to 180 cm cube. Right, so we can write that the answer that is the volume of a packet containing 12 such boxes is 180 cm cube. So this is the required answer to the session. Hope you enjoy and understood the concept well. Bye for now.
