How you would measure the volume of a box of tissue?

Answer 1

The same way you measure the volume of any other box,

or any other rectangular prism:

-- Measure the length.

-- Measure the width.

-- Measure teh height.

-- Multiply (length) x (width) x (height).

The product is the volume of the box.

Answer 2

The same way you measure any box.

I would multiply the height of the box by the length of the box and that by the width of the box.
