Density of steel, cement, sand, and ratio of concrete mix are important factors in construction.

• Density of steel is around 7850 kg/m^3.

• Density of cement is around 1440 kg/m^3.

• Density of sand is around 1600 kg/m^3.

• Ratio of concrete mix varies depending on the strength required, common ratios are 1:2:4 (cement:sand:aggregate) for general use.

• Density = Mass/Volume, so density can be calculated by knowing the mass and volu

Quantity measurement of structure involves determining the amount of materials needed for construction.

• Calculate the volume of the structure by multiplying the length, width, and height.

• Estimate the quantity of materials such as concrete, steel, and bricks required based on the structural design.

• Consider factors like wastage, reinforcements, and formwork when calculating quantities.

• Use software tools like AutoCAD or Ex
