If you notice the terms, they're
7, -21, 63, -189 and so forth.
7*-3 = -21 and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.
now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 , you do have a convergent sequence.
however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.

Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm
Area of the top = area of the base = 64.5cm
Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm
Total surface area = 64.5 + 64. 5+ 330 = 459 cm²
