Because you are looking for square inches of wrapping paper, you are looking for the surface area of the box. A three-dimensional box has a top and bottom that are the same size, a front and back that are the same size, and 2 sides that are the same size...or SA = 2(top/bottom area) + 2(front/back area) + 2(side/side area). Our equation fills in nicely like this:
SA = 2(6 * 14) + 2(6 * 8) + 2(14 * 8)
SA = 2(84) + 2(48) + 2(112)
SA = 168 + 96 + 224
SA = 488 square inches of paper to wrap the box.

Step-by-step explanation:
Yes, rhombus is always a quadrilateral. We know that rhombus is a parallelogram and in order for a shape to be a parallelogram, it needs to have four sides and angles.
The formula of the midpoint of PQ:
We have P(0; 0) and Q(2a; 0). Substitute:
