The net of a triangular prism is shown below. Each of the bases is shaped like an isosceles triangle. 20 cm 5 cm 4 cm 6 cm 5 cm What is the total surface area of the triangular prism in square centimeters ?

320

Step-by-step explanation:

320

Step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
