A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 8 inches, a width of 2 inches, and a height of 3 1/2 inches. What is the surface area?

State if the two triangles are congruent. if they are, state how you know?

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
