Cube mould size is a standard size used for testing the compressive strength of concrete.

• Cube moulds are typically made of steel or cast iron.

• The standard size for cube moulds is 150mm x 150mm x 150mm.

• Other sizes such as 100mm x 100mm x 100mm and 200mm x 200mm x 200mm are also used.

• The moulds are filled with concrete and left to cure before being tested for compressive strength.

• Cube moulds are used to ensure that the c...read more

To calculate the weight of an 8mm diameter steel rod, use the formula: weight = volume x density.

• Calculate the volume of the rod using the formula: volume = π x (diameter/2)^2 x length

• Find the density of steel, which is typically around 7850 kg/m^3

• Multiply the volume by the density to get the weight of the rod
