The cover of a book has an area of 400 cm², the book has a heigh of 4 cm. what
is the books volume? use the
correct unit for volume in your awnser.

1600cm³

Explanation:

The volume of a cuboid can be calculated as follows;

V = L × B × H

Where;

L = length (cm)

B = breadth or width (cm)

H = height (cm)

However, in this question, the area of the book is said to be 400cm². Since area of a rectangle or rectangular-shaped object like the book is L × B, this means that the length and breadth has been combined in the area. Hence;

Volume of the book = area of the book (L × B) × Height of the book (H)

Volume = 400cm² × 4cm

Volume = 1600cm³

Therefore, the volume of the book is 1600cm³.
