Greg is recovering one of his couch cushions. The cushions is in the shape of a rectangular prism. Greg drew the net of the cushion below

have you found out the answer yet

Answer:320 sq in

Step-by-step explanation:

To calculate how much fabric is needed to cover the cushion, add the area of each rectangular section.

l = 12 in, w = 7 in, h = 4 in

Rectangle 1 area (l * h) : 12 in * 4 in = 48 sq in

Rectangle 2 area (w * h) : 7 in * 4 in = 28 sq in

Rectangle 3 area (l * w) : 12 in * 7 in = 84 sq in

Rectangle 4 area (w * h) : 7 in * 4 in = 28 sq in

Rectangle 5 area (l * h) : 12 in * 4 in = 48 sq in

Rectangle 6 area (l * w) : 12 in * 7 in = 84 sq in

Now, add all the areas together.

48 sq in + 28 sq in + 84 sq in + 28 sq in + 48 sq in + 84 sq in = 320 sq in
