The length of one edge of the triangular pyramid is 6 cm
How to determine the length L?
The area is given as:
Area = 240 square centimeters
The net of the triangular pyramid consists of:
- 4 triangles
- Each triangle has the same base (L) and height (10)
So, the area of the net is:
Area = 4 * Base * Height
This gives
240 = 4 * L * 10
Divide both sides by 40
L = 6
Hence, the length of one edge of the triangular pyramid is 6 cm
