Question

Work out the surface area of the triangular prism below. Give your answer in cm². ​

Answer 1

To find the surface area of the triangular prism, calculate the areas of the triangular bases and the lateral faces.

Step-by-step explanation:

To find the surface area of the triangular prism, we need to find the areas of the triangular bases and the lateral faces. The formula for the area of a triangle is 1/2 × base × height. Given the dimensions of the triangle, we can calculate the area. Once we have the area of the triangular bases and the perimeter of the triangular bases, we can find the lateral surface area by multiplying the perimeter by the height of the prism.

Answer 2

540 cm²

Step-by-step explanation:

`(13)(16)+(1)/(2)(2)(12)(5)+(12)(16)+(16)(5)=540`
