Question

Each book is the same size is sold he knows the area of the base of one book is 22 1/2 in.² in each book is 3/4 inches thick the volume of a stack of nine bucks is blank cubic inches

Answer 1

The volume of a stack of nine bucks is
`(1,215)/(8)`cubic inches

Explanation:

Area of the base of one book , A=
`22 (1)/(2) inch^2=(45)/(2) inch^2`

Height of 1 book = h =
`(3)/(4) inches`

If nine books are stacked together then height of the stack will be :H

H =
`9* (3)/(4) inches=(27)/(4) inches`

So, volume of the stack = V

V = Area of the base × H

Area of base = area of base of the 1 book = A

`V=A* H=(45)/(2) inch^2* (27)/(4) inches=(1,215)/(8)inch^3`

The volume of a stack of nine bucks is
`(1,215)/(8)`cubic inches
