Q2. How to find triangle concrete quantity.
Ans. 
Triangle concrete quantity can be found using the formula: 1/2 * base * height * thickness.
• Calculate the area of the triangle using the formula: 1/2 * base * height.

• Multiply the area by the thickness to get the concrete quantity.

• For example, if the base of the triangle is 5 meters, height is 8 meters, and thickness is 0.2 meters, the concrete quantity would be: 1/2 * 5 * 8 * 0.2 = 4 cubic meters.

Q4. 1m^3 how many bricks
Ans. 
The number of bricks in 1m^3 depends on the size of the bricks being used.
• The number of bricks in 1m^3 will vary based on the size of the bricks.

• Calculate the volume of a single brick and then divide 1m^3 by that volume to get the number of bricks.

• For example, if a brick is 0.2m x 0.1m x 0.05m, its volume would be 0.001m^3. Therefore, 1m^3 would contain 1000 bricks.
