what formula do you use for calculating the volume of a box?

I think it is V=lwh

Right.

Ithink that it's right too.

You are correct! The formula for calculating the volume of a box is V = lwh, where V represents the volume, l represents the length, w represents the width, and h represents the height of the box. To find the volume of a box, you simply multiply the length, width, and height together.
