Not sure exactly what you want but our garage was built a few years ago with a trapezium base (to fit the land space available to the side of our house).
The footings were a fairly normal trench style with deeper parts at the corners and under the rear doors' pillars location (our garage is about 9 ft wide at the front but about 18 ft wide at the back). The volume of these footings were the volumes of the cuboids along each side plus the volume of the corners - the slight non-90o corners makes little difference in the amount of concrete that has to be ordered.
For the slab on top, its volume is the area of the trapezium times the depth of the slab (all in the same units):
volume_slab = (12 x sum_of_parallel_sides x perpendicular_distance_between_those_parallel_sides) x depth_of_slab
If you have trapezium shaped footings, then I guess you have a footing with a trapezium cross-section: use the volume_slab formula above with appropriate choices for the parallel sides (of the trapezium) and the depth_of_slab would be the length_of_footing.

How do you find the volume of a trapezium?
A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
How do you calculate the number of sweets in a jar?
Calculate the volume of one sweet. Calculate the volume of the jar and then divide the volume of the jar by the volume of a sweet.
What is the equation for volume of 3D trapezium?
The volume is the Area multiplied by thickness (if the thickness is constant). Area = 1/2 ((a+b)*h) a = the base length b = the top length h = the height (constant) t = the thickness (constant) Volume = Area*t Please note that a trapezium and a trapezoid are defined differently in England and the USA. In England the trapezium has the base and top parallel and the area calculation above is for that definition but the area calculation for a trapezoid is different. The volume will still be Area*t.
What is the relationship between the area of a parallelogram and the area of a trapezium?
The formulae are quite similar; you multiply base x height, where the height is perpendicular to the base. In the case of a trapezium, you need to calculate the average of the two bases first.
Volume of a trapezium?
None but if you mean area it is: Area measured in square units = 0.5*(sum of parallel sides)*height
How do you calculate the volume of a trapezium prism?
1/2 h(a+b)
How you calculate for the perimeter of a trapezium?
yes u can calculate the perimeter of a trapezium
How do you find the volume of a trapezium?
A trapezium is a 2D shape; volume it an attribute of 3D shapes. The volume of all trapezia is 0.
How do you calculate the volume of concerete needed for trapezoidal footing?
Volume = cross-section area*depth Area of a trapezoid = 0.5*(sum of parallel sides)*width
How do you calculate the centroid of a trapezium when using a geometic picture?
How do you calculate the centroid of a trapezium when using geometic picture
What is the volume of a trapezium a5.80 b6.50?
A trapezium is a 2-dimensional shape and so has no volume. If you were thinking of area, there is not enough information to answer.
How do you calculate of steel in beam and footing?

What is the volume and area of an isosceles trapezium?
The area of a trapezium is given by 0.5*(a+b)*h where a and b are the lengths of the parallel sides and h is the vertical distance between them. The fact that the trapezium is isosceles does not matter. A trapezium is a 2 dimensional object and so it has no volume.
How do you find volume of trapezoid shaped RCC footing?
(a1+a2+sqrt(a1*a2)*h/3= volume of Trapezoid RCC Footing
What is the formula for calculating volume of ecentric footing?
Volume = Height*Width*Length
Calculate footing size for steel building?
Footing Size 3'9" x 3'9" C/C 6"
How do you calculate quantity of isolated sloped footing?
You can calculate the quantity of isolated sloped footing by substituting variables for what you are trying to solve for. For instance, substitute x for rise and y for run.
