In construction, metal weight is crucial for ensuring structural safety, stability, and cost efficiency. Accurate weight calculations help prevent failures, manage costs, and ensure materials meet design and safety standards.

General Formula for Metal Weight:

$\text{Weight} = \text{Volume} \times \text{Density}$

Where:

Weight is in kilograms (kg), grams (g), or other units depending on the density unit.
Volume is in cubic meters ( $m^3$ ) or cubic centimeters ( $cm^3$ ), etc.
Density is the material's density in units like $g/cm^3$ or $kg/m^3$

For a Rectangular Metal Block:

If the shape is a rectangular block, the volume can be calculated as:

$\text{Volume} = \text{Length} \times \text{Width} \times \text{Thickness}$

Combined Formula for Weight:

$\text{Weight} = \text{Length} \times \text{Width} \times \text{Thickness} \times \text{Density}$

Example Calculation:

Let's calculate the weight of an aluminum block with:

Length = 2 m
Width = 1 m
Thickness = 0.1 m
Density = 2700 $kg/m^3$ (density of aluminum)

Volume Calculation:

$\text{Volume} = 2 \, \text{m} \times 1 \, \text{m} \times 0.1 \, \text{m} = 0.2 \, m^3$

Weight Calculation:

$\text{Weight} = 0.2 \, m^3 \times 2700 \, \frac{kg}{m^3} = 540 \, kg$

For Cylindrical Metal Rods:

If the shape is a cylinder, the volume is given by:

$\text{Volume} = \pi \times r^2 \times h$

Where:

r = radius of the base
h = height (length) of the cylinder

Combined Formula for Weight:

$\text{Weight} = \pi \times r^2 \times h \times \text{Density}$

Example Calculation for a Cylinder:

Let’s calculate the weight of a copper rod with:

Radius = 0.05 m
Height = 1 m
Density = 8960 kg/m3kg/m^3
kg/m3

Volume Calculation:

$\text{Volume} = \pi \times (0.05 \, \text{m})^2 \times 1 \, \text{m} = \pi \times 0.0025 \, m^2 \times 1 \, \text{m} = 0.00785 \, m^3$

Weight Calculation:

$\text{Weight} = 0.00785 \, m^3 \times 8960 \, \frac{kg}{m^3} = 70.37 \, kg$

These formulas can be adapted to calculate the weight of any metal shape by substituting the appropriate volume formula for the shape.
