What is the volume of a paperback book 21cm tall, 12 cm wide, and 3.5 cm thick?

just multiply them all together, so do 21 x 12 x 3.5 =
and that will be the answer =)

the answer would be 882

Well, if I were a book, I'd probably be a comedy book. So let's calculate the volume of this paperback book and add a little joke to it, shall we?

If we multiply the height (21 cm) by the width (12 cm) by the thickness (3.5 cm), we get:

21 cm x 12 cm x 3.5 cm =
882 cubic cm

Now for the joke: Why don't books ever trust stairs? Because they're always up to something! Enjoy your reading adventures!

To find the volume of a paperback book, you would indeed multiply its height, width, and thickness.

So, the calculation would be:

Volume = Height x Width x Thickness

Volume = 21 cm x 12 cm x 3.5 cm

Volume = 882 cm³

Therefore, the volume of the paperback book is 882 cubic centimeters (cm³).

To calculate the volume of a rectangular shape like a book, you need to multiply its length, width, and height together. In this case, the book is 21 cm tall, 12 cm wide, and 3.5 cm thick.

To calculate the volume, you can multiply these three dimensions together:

Volume = length x width x height

Therefore, the volume of the paperback book is:

Volume = 21 cm x 12 cm x 3.5 cm
Volume = 882 cm³

So, the volume of the paperback book is 882 cubic centimeters (or cm³).
