A "regular quadrilateral" is a square.

How many side does a square have?

If its perimeter is 60 cm, what is the length of each side?

The prism has two bases; the surface area of each one is the square of the side length of the square.

How many lateral faces does the prism have? The area of each one is given as 105 cm^2; what is the total lateral surface area?

And finally, what is the total surface area, counting bases and lateral faces?
