Q1. What is cube of weight
Ans. 
Cube of weight refers to the volume occupied by an object based on its weight.
• Cube of weight is a concept used in logistics and transportation.

• It helps determine the space required to store or transport an object based on its weight.

• The formula to calculate cube of weight is weight (in pounds) divided by the weight per cubic foot (in pounds).

• For example, if an object weighs 100 pounds and has a weight per cubic foot of...read more

Q2. What is steel weight of 8 mm 1m
Ans. 
The weight of 8 mm steel rod with 1 meter length.
• The weight of steel can be calculated using the formula: weight = volume × density

• To calculate the volume of a rod, use the formula: volume = π × (diameter/2)^2 × length

• The density of steel is typically around 7850 kg/m^3

• In this case, the diameter of the rod is 8 mm, which is equivalent to 0.008 meters

Q3. What is the ratio of m25
Ans. 
The ratio of M25 refers to the mix proportion of concrete used in construction.
• M25 is a grade of concrete commonly used in construction.

• The ratio of M25 is 1:1:2, which means 1 part cement, 1 part fine aggregate (sand), and 2 parts coarse aggregate (stone).

• This ratio ensures the desired strength and durability of the concrete mix.

• For example, if we need to make 1 cubic meter of M25 concrete, we would use 1/4 cubic mete...read more
