To sign 'box', use flat hands to outline the shape of a box. First, hold your hands parallel in front of you with your palms facing each other and fingers pointing forward, indicating the sides. Then, reposition your hands so one is closer to your chest and the other is further away, with palms facing each other, to show the front and back walls of the box.
Sign 'box' to establish the object, then use the sign for 'put in' by moving your dominant hand into the space you just outlined.
To show the size, sign 'box' but expand the distance between your hands significantly to emphasize that it is a large box.
Sign 'box', then use the sign for 'empty' by sliding your dominant middle finger across the back of your non-dominant hand.

You can easily modify this sign to show size. For a small box, keep your hands close together. For a large box, start with your hands wider apart and make the front-to-back motion larger, accompanied by an appropriate facial expression.
They are very similar because both outline a square or rectangular space. However, 'room' is typically signed slightly larger and often uses 'R' handshapes in some variations, while 'box' uses flat hands and is usually signed smaller.
Generally, your non-dominant hand stays closer to your body while your dominant hand moves further away to show the front wall of the box, but the sign is understood either way as long as the shape is clear.
