Final answer:
To find the volume of the book with a cover area of 450 cm² and a height of 4 cm, multiply these two values resulting in a volume of 1800 cm³.
Step-by-step explanation:
The student is asking how to calculate the volume of a book. The cover of the book has an area of 450 cm² (centimeters squared), and the book has a height of 4 centimeters. To find the volume of the book, we use the formula for the volume of a rectangular prism, which is the area of the base times the height (V = Ah).
In this case, the area of the base (A) is already provided as 450 cm². The height (h) is given as 4 centimeters. Therefore, the volume (V) is calculated as 450 cm² multiplied by 4 cm which equals to 1800 cm³ (centimeters cubed). This is the volume of the book.
