Pls help I’m confused

I’m confused too that’s hard

It’s 148. So you just want the surface of all the sides combined so you have to find the surface of each side. There are six sides but they each have an opposite side that is equal so you find the surface of each side and add em all together. There are two sides that are 5x6 so you calculate that and get thirty but since there’s two you then multiply it by 2 and get 60. Then you do it with the other sides that are 4x6 and 5x4 when you calculate those and multiply them by two you get 48 and 40. Adding them all together you get 148.
