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.
