Ответ:
A = 4×(1/2)×b×h
A = 2×(8 cm)×(6.9 cm)
A = 110.4 cm²
The surface area of the triangular pyramid is 110.4 cm².
Ответ:
We have then that the surface area is:
A = (4) * (1/2) * (b) * (h)
Where,
b: base of the triangle
h: height of the triangle
Substituting values:
A = (4) * (1/2) * (8) * (6.9)
A = 110.4 cm ^ 2
The surface area of the triangular pyramid is:
A = 110.4 cm ^ 2
