Answer:
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.
