Question

Знайдіть площу поверхні трикутної піраміди якщо кожне з її ребер дорівнює 5 см

Answer 1

Площадь правильного прямоугольника  = (а^2√3)/4.
таких треугольников 4 (3 боковых и 1 основание) 
  (а^2√3)/4 * 4 = а^2√3 = 25√3

Answer 2

Finding the Surface Area of a Triangular Pyramid

To find the surface area of a triangular pyramid, we need to know the length of each of its edges. In this case, each edge of the pyramid is given as 5 cm.

The formula for finding the surface area of a triangular pyramid is:

Surface Area = Base Area + Lateral Area

The base area is the area of the triangular base, and the lateral area is the sum of the areas of the three triangular faces.

To calculate the base area, we need to know the length of the base and the height of the triangle. However, this information is not provided in the question. Therefore, we cannot calculate the exact surface area of the triangular pyramid without additional information.

If you have the length of the base and the height of the triangle, please provide those values, and I will be happy to help you calculate the surface area.
