Answer is 197.2 cm^2 is your surface area

Step by step

Break the figure down

You have a bottom, a left side, a top and two right triangle ends

Your formulas are
Rectangle Area = L x W
Triangle Area = 1/2bh

Solve
Bottom = 7 x 10 = 70 cm^2
Left side = 3 x 10 = 30 cm^2
Top = 7.62 x 10 = 76.2 cm^2
Triangle = (1/2)(3)(7) =10.5 cm x 2 triangles =21 cm ^2

Add your figures together

70 + 30 + 76.2 + 21 = 197.2 cm^2 is your surface area
