The image above represents TEX.

To compute for TEX, two essential parameters are needed and these parameters are **mass (M) **and **length (L).**

The formula for calculating TEX:

TEX = ^{M}/_{L} x 1000

Where:

TEX = TEX

M = Mass

L = Length

Let’s solve an example;

Find the TEX when the mass is 8 and the length is 14.

This implies that;

M = Mass = 8

L = Length = 14

TEX = ^{M}/_{L} x 1000

TEX = ^{8}/_{14} x 1000

TEX = 0.57 x 1000

TEX = 571.4

Therefore, the **TEX **is **571.4.**

**Calculating the Mass when the TEX and the Length is Given.**

M = ^{TEX x L} / _{1000}

Where:

M = Mass

TEX = TEX

L = Length

Let’s solve an example;

Find the mass when the TEX is 40 and the length is 8.

This implies that;

TEX = TEX = 40

L = Length = 8

M = ^{TEX x L} / _{1000}

M = ^{40 x 8} / _{1000}

M = ^{320} / _{1000}

M = 0.32

Therefore, the **mass **is **0.32.**

**Calculating the Length when the TEX and the Mass is Given.**

L = ^{M1000} / _{TEX}

Where;

TEX = TEX

M = Mass

Let’s solve an example;

Find the length with a TEX of 50 and a mass of 20.

This implies that;

TEX = TEX = 50

M = Mass = 20

L = ^{M1000} / _{TEX}

L = ^{(20)1000} / _{50}

L = ^{20000} / _{50}

L = 400

Therefore, the **length **is **400.**
