no you multiply
That's going to depend on what you'll use the volume to find.There's no single rule that you can use every time you see volume.
You are supposed to multiply the length by the edge that is a fraction and divide it by 2 and multiply by 3. Then you add 3.14. You should get your answer
You measure the height and the length and add them together. Multiply the result by the square root of the width. That number, in cubic units, is the volume.
You have to multiply to find area you have to add to find perimiter
you are suppose to MULTIPLY on area.
That is correct for finding the volume of a cylinder.

you can multiply 281 and 3 you can add 840 and 3
The answer depends on what you wish to multiply the volume by!
