How To Calculate Concrete Volume Of Trapezoidal Footing Quantity Of How to calculate the concrete quantity of a trapezoidal footing? an isolated footing area may be in rectangular or square shape. we have explained the process for both shapes. first, we have to calculate the below rectangular part separated by the dotted line (refer the diagram), using rectangular area formula. It determines the amount of concrete required to form the footing. the formula to calculate the volume of a trapezoidal footing is: volume = (a 1 a 2) × b × h 2. where: volume is the total volume of the trapezoidal footing, measured in cubic units (e.g., cubic meters or cubic feet). a1 and a2 are the areas of the two bases of the.

How To Calculate Trapezoidal Footing Volume Trapezoidal Footing Trapezoidal volume calculation formula. the below formula is used to calculate the volume of the trapezoidal footing. v = h 3 (a1 a2 (√a1 x a2) a1 = area of lower portion. a2 = area of upper portion. h = height of trapezoidal portion. Trapezoidal footing = cuboid trancated pyramid. so to calculate the volume of trapezoidal footing we need to calculate the volume of a cuboid and a truncated pyramid. 1. volume of rectangular cuboid = length x breadth x height = 3 x 2 x 0.3 = 1.8 m³. 2. volume of truncated pyramid = 1 3 (a1 a2 √a1a2) x h. where a1 = area of the top base. Plan and elevation of trapezoidal footing. 1. the volume of the truncated pyramid is given by, from figure 2, ht = height of the pyramid a1 = area of the bottom surface of the pyramid a2 = area of the top surface of the pyramid a1 = a x b a2 = a x b 2. the volume of a cuboid is given by, from figure 2, a = length of the cuboid b = breadth of. A trapezoidal footing volume calculator uses a specific formula to compute the volume of concrete required based on the dimensions of the trapezoidal footing. the calculation process involves the following steps: 1.input footing dimensions. top length (l1): the length of the trapezoid’s top (narrower) side. bottom length (l2): the length of.
