Question

Use the net to compute the surface area of the three-dimensional figure. A) 210 units2 B) 225 units2 C) 240 units2 D) 280 units2

Answer 1

It is A, because you have to multiple 8 and 5. Which is 40. Then you have to multiple 40 and 4 together because you have 4 rectangles. You then have to multiple 5 and 5. You get 25 and you have to multiple that by 2. then you have 160+50=210
