For the face, base and altitude of the \*Sautrā-maṇikī-vedi\* which is of the shape of an isosceles trapezium, are stated, it has been noted before,¹ to be respectively 24/√3, 30/√3 and 36/√3 prakramas, or to be 8√3, 10√3 and 12√3 prakramas. Hence it is clear that the ancient Hindus knew that $24/(√3) = 8√3, 30/(√3) = 10√3, 36/(√3) = 12√3.$ - [Previous: c19.s2.30](https://indike.org/pramana/ins.science.datta-1932.c19.s2.30) - [Next: c20.3](https://indike.org/pramana/ins.science.datta-1932.c20.3) - [Up: c20](https://indike.org/pramana/ins.science.datta-1932.c20) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c20.2](https://indike.org/pramana/ins.science.datta-1932.c20.2) · Pramāṇa
