Let A,B,C,D Four different sides with different lengths. Apply the following formula.
A = Sqrt ( ( s-a) ( s-b) (s-c) (s-c) )
Where S = ( a+b+c+d) / 2.
You measure the sides, and multiply the top and side.
The usual form for the area of a trapezoid is (average of the parallel sides) x height. If only the lengths of the sides are given, then calculation of the area requires trigonometry and multiple solutions are possible. Often, teachers will give a problem like this showing the two unequal parallel sides and two unequal, non-parallel sides with a diagram showing that one of the sides is perpendicular to the parallel sides. That side length would be the height.
surface area divided by volume
To calculate the surface area of a truncated pyramid, you first take the surface area of each side. That would be the base time the straight height. If it is a 4 side pyramid with equivelant sides, multiply that answer by 4.
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.

Surface area if a cube with six sides can be calculated by finding the surface area of one side and then multiplying the result by 6.
Add the areas of all the faces (Flat sides).
You measure the sides, and multiply the top and side.
To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.
You can think of a square prism as a die, having six sides. So you need the length of one side, 's'. That side's [surface] area is s2 With six sides, the cube's surface area is simply: 6s2

If a cube has sides of length x cm then area = 6x2 cm2 and volume = x3 cm3
The surface area of a prism is the sum of the areas of each of its sides, plus the two bases. As the number of sides, and their shapes are indeterminate, there is no specific formula. The general formula is (2 x base area) + (perimeter x length)
to calculate the area of the front surface of a box you should
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
You need to know the lengths of the sides and at least one angle or the length of a diagonal.
