![]() Then apply the formula above or use our area of a trapezoid calculator online to save time and have a higher chance that the result is error-free (bad input will certainly result in bad output). Measure the height and make the necessary metric conversions until all three lengths are in the same units. ![]() Then, build the height using a right angle with a tip at any of the bases and using that base as one of its arms. To make the calculation, first, measure the two bases. If you measured in centimeters, the result will be in square centimeters, and so on for square inches, yards, miles, as well as square meters, kilometers. The total surface area of the cylinder 2 r(r+h), where r is the radius of the circular base and h is the height of the cylinder. So, if you measured in feet, the result will be in square feet. The result is always in the length unit used - but squared. In order to use our area of a trapezoid calculator, you need to take three measurements, all in the same units (convert as necessary). The calculation essentially relies on the fact a trapezoid's area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area. The 3D figure of a trapezoid is called a trapezoidal prism since these are figures that have a length, width, and depth. The edges of the prism is where the faces meet, and the vertices of the prism are the corners where three or more surfaces meet.The formula for the area of a trapezoid is (base 1 + base 2) / 2 x height, as seen in the figure below: ![]() Where A is the area, h is the height, a and b are the lengths of the base trapezoids Why is the Trapezoidal Prism a 3D Figure? Since the prism has two trapezoids, to calculate the volume we need to find the height of one of the trapezoids using this formula: But when the slant height is known instead of the actual height, then a different formula needs to be used. Mostly, the calculations can be done if only the bottom and top width, height, and length are known. In order to find the height of a trapezoidal prism, we need to find the area of one of the trapezoids. The following section will give you a step-by-step explanation of calculating the volume of a trapezoidal prism and its formula. How do you Find the Height of a Trapezoidal Prism? When the trapezoidal prism is flattened, we can see these two images clearly. The net of a trapezoidal prism is that it consists of two trapezoids and four rectangles. Where h is the height, b and d are the lengths of the base, a + b + c + d is the perimeter, and l is the lateral surface area. Surface Area of a Trapezoidal Prism = h (b + d) + l (a + b + c + d) The formula to calculate the surface area of a trapezoidal prism is: ![]() Example: Find the Volume of Trapezoid when the bases are 4 cm and 3 cm, height is 6 cm and slant height is 8 cm then calculate the volume of trapezoid prism. a and b are the lengths of the trapezoidal bases, h is the height, l is the slant height. ![]() Where h is the height of trapezoidal, l is the height of the prism, a and b are the lengths of the top and bottom of a trapezoidal prism What is the Formula to Calculate the Surface Area of a Trapezoidal Prism? Trapezoid Volume Formula is given as: V 1/2 × (a+b) × h × l. The formula to calculate the volume of a trapezoidal prism is:Īrea (A) = ½ × h × (a + b) or ½ h(b 1+ b 2) To find the volume of a trapezoidal prism, we need to first find the area of one trapezoid. What is the Formula to Calculate the Volume of a Trapezoidal Prism? One of the box noticeable example of a trapezoidal prism that we see in daily life is fire brick. A trapezoidal prism was given its name since it is made up of trapezoids. A trapezoidal prism has six faces, eight vertices, and 12 edges. FAQs on Trapezoidal Prism What is a Trapezoidal Prism?Ī trapezoidal prism is a 3D shape with two trapezoids as its base that is being joined by four rectangles. ![]()
