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
