Answer to Problem 29LC

The volume of a paperback book is $42{\text{cm}}^{\text{3}}$ .

Explanation of Solution

Any sample of matter takes up space, which is known as volume. The volume of cubic solid is obtained by the multiplication of length by width by height.

The formula of volume is given as,

  $\text{V}=\text{length×width×height}$

The given length is $21\text{cm}$ .

The given width is $12\text{cm}$ .

The given height is $3.5\text{cm}$ .

To calculate the volume, substitute the values in the above equation.

  $\begin{array}{c}\text{V}=\text{length×width×height}\\ =\text{21}\text{cm}\times \text{12}\text{cm}\times \text{3}\text{.5}\text{cm}\\ =\text{42}{\text{cm}}^{\text{3}}\end{array}$
