A triangular prism. The rectangular sides are 2.5 millimeters by 8 millimeters, 8 millimeters by 6.5 millimeters, and 8 millimeters by 6 millimeters. The 2 triangular sides have a base of 2.5 millimeters and height of 6 millimeters.

The triangular prism shown has triangular face(s) and lateral face(s).

The area of one triangular face is mm2.

The surface area of the triangular prism is mm2.

One triangular face = 7.5mm2

Surface area=135mm2

Step-by-step explanation:

Area of a triangle (1/2)(bh) so (1/2)(2.5*6)=7.5

The area of the first rectangle is 20 (2.5*8)

The second rectangle is 52 (6.5*8)

The third rectangle is 48 (8*6)

Then you take the area of one triangle and multiply it by 2, which equals 15.

Then you add it all together and get 135

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
