Question

Ms. Sue · Accepted Answer

That's an awfully slim math book. Are you sure it's only 0.78 cm thick? 0.78 * 21 = 16.38 cm

Bun · Answer

This is so easy and I'm a fourth grader. All you have to do TJ is to multiply 78 by 21

Doggo · Answer

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
