You must be thinking of a triangular prism. In that case, c is the length of the third side of the triangle at the end of the prism.
Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c
area of base x height area of base x height
There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
I dont know:d
its not i dont no why
Volume = 1/2*(a+b)*h*l where a and b are the lengths of the parallel sides of the trapezium, h is the height of the trapezium, and l is the length of the prism.
If you mean volume of a trapezoidal prism then it is: 0.5*(sum of parallel sides)*height*length
I am not sure that a rectangular prism is in any position to care!
Surface Area = 2 × Base Area + Base Perimeter × Length
the volume of a trapezoidal prism is equal to the height times the base area of the trapezoid. First you find the area of trapezoid h(a+b)/2 h is the height of the trapezoid, not the height of the prism a is the length of the top b is the length of the bottom Then you find the volume of the trapezoidal prism with this formula H*h(a+b)/2 H is the height of the prism. Multiply H by the area of the trapezoid that you found in step one.
A trapezoidal prism has 8 vertices:A trapezoid has 4 vertices.A trapezoidal prism is composed of 2 trapezoids. 2 X 4 = 8.
It is helpful because when you do the problem you know what to do.
