It is known that the length of the side edge of the regular trigonometric vertebra is 10 cm, and the angle between the side edge and the bottom is arcsin3 / 5. The volume of the trigonometric pyramid can be calculated RT

96 pieces 3
The angle between the side edge and the bottom is arcsin3 / 5 and the height is 6
The height of 2 / 3 of the bottom regular triangle is 8, and the area of the triangle is 48 pieces of 3
V = 1 / 3SH = 96 pieces 3

This paper presents an algorithm for calculating the volume of s-abc triangular pyramid

One half of the diagonal of the bottom surface can be found to know the side edge
Then we can find the height
Then the bottom area can also be calculated, and the result will come out
You said algorithm
Wrong topic 3 pyramid ah, that directly find the base circumscribed circle radius can still be found
Then ask me online just like before
