Answer:
3220 cm²
Step-by-step explanation:
Lets find the area of the two triangles
I am making a modification:
Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2
Area of triangles = 15 cm x 28 cm = 420 cm²
Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²
Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²
Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²
Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²
If my answer is incorrect, pls correct me!
