Q1. What is volume of concrete?
Ans. 
The volume of concrete refers to the amount of space occupied by concrete.
• Volume of concrete is measured in cubic units (e.g., cubic meters or cubic feet).

• It is calculated by multiplying the length, width, and height of the concrete element.

• For example, if a concrete slab has a length of 5 meters, width of 3 meters, and height of 0.15 meters, the volume of concrete would be 5 x 3 x 0.15 = 2.25 cubic meters.
