– Space (A) is the cross-sectional space of the tube (in m² or ft²).
– Size (L) is the size of the tube (in meters or toes).
To calculate the burden of a sq. tube, observe these steps:

- Subsequent, discover the density of the tube materials. Typical values for metal (kg/m³) are 7850-7850 kg/m³ and aluminum (kg/m³) are 2707-2850 kg/m³.
- Multiply the density by the cross-sectional space to acquire the burden per unit size: ρ × A = (7850 kg/m³) × (0.005 m²) = 39.25 kg/m.
- Lastly, multiply the burden per unit size by the tube size to find out the overall weight: W = (39.25 kg/m) × 100 m = 3925 kg (rounded to the closest entire quantity).
Precision is essential in these calculations, as small variations in density and space may end up in important variations within the calculated weight.
