I^32=......................

1 answer:

5 0

I^32 = (i^4)^8 and i^4 = 1

so (i^4)^8 =1^8 = 1

The trick on all questions like this is to get as many i^4’s out of the way, since they’re all just 1s.

Find the surface area of the prism.

Vanyuwa [196]

Answer:

400cm²

Step-by-step explanation:

Total surface area of a prism includes the area of the top and bottom triangle sides of the prism, plus the area of all 3 rectangular sides.

Base & Bottom triangle area: 2 x [(8 x 15)/2] = 120cm²

Side triangle area: 17 x 7 + 8 x 7 + 15 x 7 = 280cm²

Total surface area = 280 + 120 = 400cm²
