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!
