This calculator calculates the surface area of a trapezoidal prism using sides of trapezoid, altitude, height values.
The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. The surface area can be given with this formula: Surface Area of Trapezoidal Prism S=a(l + h) + b(l + h) + lc + ld. The base of a prism is always the trapezoid for a trapezoidal prism.
Formula:
S=a(l + h) + b(l + h) + lc + ld
where,
a, b, c, d are sides of the trapezium.
h is Altitude and l = Height of the prism.
