<p>There are 6 flat surfaces or faces on a rectangle. Just find something rectangular at home and count how many flat surfaces there are and you will get why.</p>

<p>oh, i thought i had to use the surface area formula of a rectangle</p>

<p>I don’t even remember the formula. Just use your logic and you will get why.</p>
