Surface Area:
A triangular prism is made up of 3 rectangles and 2 triangles.
Area of a rectangle = base x height
Area of a triangle = 1/2 x base x height
Rectangle: 5.6 x 2.7 = 15.12
All 3 rectangles: 15.12 x 3 = 45.36
Triangle: 1/2 x 2.7 x 2.3 = 3.105
Both triangles: 3.105 x 2 = 6.21
Surface Area: 45.36 + 6.21 = 51.57 mm^2
Volume:
Volume of a triangular prism = base area x height
Triangle area = 3.105
Height = 5.6
Volume: 3.105 x 5.6 = 17.88mm^3
Hope this helps!
