Answered by Ms. Sue
That's an awfully slim math book. Are you sure it's only 0.78 cm thick?

0.78 * 21 = 16.38 cm

This is so easy and I'm a fourth grader.


All you have to do TJ is to multiply 78 by 21

Okay! DO THIS!

0.78 x 21 = t

t = YOUR ANSWER!

That's all you gotta do! Have a good day, or night!

Also, if you wanna know what t is-

t = 16.38

I think- I may not be correct-

If you ever get a question that says a piece of information and then asks how many, what width, what number, etc. would blank be you are multiplying.

Piece of info: One book is .78 cm wide.

What width: What width would 21 books be?

.78 x 21 = 16.38
