It’s not 100 points it’s only five points
-2 or -2/1 because the ratio is y over x and the line is going down 2 (-2) every time it goes to the right once (1)

Because the shape is a cube, we know that all sides must be 5cm. To find the area of a side, you do base × height, so 5 × 5 = 25. If you look at the net, you'll notice that there are 6 faces, which means you have to do 25 × 6 = 150cm^2. I hope this helps!
