Find the volume of a book whose length 19cm, width is 12cm and thickness is 3cm.

93cm^3

285cm^3

684cm^3

34cm^3

To find the volume of the book, we need to multiply the length, width, and thickness:

Volume = Length × Width × Thickness

= 19 cm × 12 cm × 3 cm

= 684 cm³

So, the volume of the book is 684 cm³!
