Question

Solve the following word problem
a. A book is 16 cm long, 12 cm wide and 2.5 cm thick.
There are 10 books placed on top of each other. What is the
volume of the stack of books?
​

Answer 1

Step-by-step explanation:

A book is in the shape of a cuboid

$volume \: of \: cuboid \: = l \times b \times h \\ = 16 \times 12 \times 2.5 \\ = 480 \: {cm}^{3}$

$volume of a stack of books = 480×10= 4800{cm}^{3}$

Therefore, volume of the stack of books is 4800cm^3

Answer 2

Answer:

4800cm^3

Step-by-step explanation:

Length of each book=16cm

Width of each book=12cm Height of each book=2.5cm

Therefore height of 10 books=10X2.5=25cm

Volume of entire book stack = 25X12X16

=300X16

= 4800

The volume of the entire stack is 4800cm^3

I hope explanation helps you.
