A book is in the shape of a right rectangular prism.
It measures 8 1/2 in. tall, 7 in. wide, and 2 1/2 in. thick.

Do you have a question about this book?

oh yeah what is the volume of the book sorry

V = lwh
V = 8.5 * 7 * 2.5
V = ________ cubic inches 
So how many cubic inches...Or how do I do it...

* means multiply

Thank you so much...Are you the only answerer on here???

And can you answer this....A rectangular prism has a length of 15 1/4 cm, a width of 8 cm, and a height of 2 1/4 cm.
Enter the volume of the prism as a mixed number in simplest form in the box. 
It looks like I'm the only one on Jiskha right now.
And you are welcome. 
Your last problem is done the same way. You can multiply the fractions. Or you can multiply the decimals and change the answer to a mixed number.

Oh wow, thanks...Have a great day

You're welcome. You too.
