Multiply by 4 to increase.
228*4=912m^2
216*4=864m^3

The triangle prism has 5 sides.
----------------------------------------------
Area of the bottom rectangle:
----------------------------------------------
Area = 6 x 7 = 42 m²
----------------------------------------------
Area of the 2 triangles:
----------------------------------------------
Area = 2 [ 1/2 x 6 x 4] = 24 m²
----------------------------------------------
Area of the 2 side rectangle:
----------------------------------------------
Area = 2 [ 5 x 7] 70 m²
----------------------------------------------
Total area:
----------------------------------------------
Total Area = 42 + 24 + 70 = 136 m²
----------------------------------------------
Answer: Surface area = 136m²
