Tetraedrning umumiy sirt maydoni:

$$S_{jami} = a^2 \sqrt{3}$$

Bir yuzning maydoni:

$$S_{yuz} = \frac{a^2 \sqrt{3}}{4}$$

Bosim ta'rifi:

$$p = \frac{F}{3 \cdot S_{yuz}}$$

Ifodani almashtirib:

$$p = \frac{F}{3 \cdot \frac{a^2 \sqrt{3}}{4}} = \frac{4F}{3a^2 \sqrt{3}}$$

{Javob:}

$$P = \frac{4}{3\sqrt{3}} \cdot \frac{F}{a^2}$$
