Answer:
Volume of the stack book is given by:
[tex]V = A \cdot h[/tex] .....[1]
where
V is the volume of the stack book.
A is the area of the stack book and
h is the height of the stack.
As per the statement:
The area of each book is 63 square inches.. The height of the stack is 15.75 inches.
⇒ Area of book(A) = 63 square inches.
and height(h) = 15.75 inches.
then;
substitute these in [1] we have;
[tex]V = 63 \cdot 15.75= 992.25[/tex] cubic inches.
Therefore, volume of the stack of books is 992.25 cubic inches
