Question

пожалуйста помогите срочно!!!!)Площадь основания треугольной прямой призмы равна 6см а площади боковых граней 12см,16см,и 20см.Найдите площадь полной поверхности призмы

Answer 1

Sполн - площадь полной поверхности, Sосн - площадь основания, Sбок - площадь боковой поверхности.

Sполн = 2Sосн + S1бок + S2бок + S3бок = 2 * 6 + 12 + 16 + 20 = 60 см²

Answer 2

Finding the Surface Area of a Triangular Prism

To find the surface area of a triangular prism, we need to calculate the sum of the areas of its bases and the areas of its three rectangular faces.

Given Information

- The area of the base of the triangular prism is 6 cm². - The areas of the three rectangular faces are 12 cm², 16 cm², and 20 cm².

Calculating the Surface Area

To calculate the surface area of the triangular prism, we can use the formula: Surface Area = 2 * Base Area + Perimeter of Base * Height

First, we calculate the perimeter of the base: Perimeter of Base = 12 + 16 + 20 = 48 cm

Then, we calculate the surface area using the given base area and perimeter of the base: Surface Area = 2 * 6 + 48 * Height

Unfortunately, the height of the prism is not provided, so it's not possible to calculate the exact surface area without this information.

If you have the height of the triangular prism, please provide it so that I can help you calculate the surface area.
