How to calculate the Volume & Surface area of Rectangular Column / Volume Of Concrete / Area Of Shuttering / Area Of Painting work

The following Article explain you that brief explanation of calculation of surface area & volume of rectangular column, surface areas used to find painting &  Shuttering areas quantities, also Volume of rectangular is used to find the concrete quantities.

Surface Area calculation / Area of Shuttering / Area of Paint for rectangular column

The surface area of a column refers to the total area that is exposed on the exterior of the column. In the context of a column, surface area typically includes both the lateral surface area (the sides of the column) and the base area.

Surface area = Total Perimeter x Height

What is Perimeter

The perimeter of a rectangle is the total length of its boundary or the sum of the lengths of all its sides. For a rectangle, which has two pairs of equal and opposite sides, the perimeter (P) can be calculated using the formula:

Perimeter =2 X (length + width)

For Example as per above drawing

Length = 600 mm / 0.60 m

Width = 400 mm / 0.40 m

Height = 5.00 m

So, Perimeter = 2(0.6+0.4) = 2.00m

Surface Area = Perimeter X Height

Surface Area = 2.00 x 5.00 = 10m²

So, the Shuttering & Painting area of rectangular column is 10 m²

Volume of Rectangular column / Concrete volume calculation for rectangular column

Volume = Area X Height

Area of Rectangle = Length x Width

Area of rectangular column is = 0.60 x 0.40 = 0.24 m²

So, Volume of Rectangular column = Area X Height

Volume = 0.24 x 5.0 = 1.2 m³

Volume of rectangular column / Concrete quantity of Column is = 1.2 m³
