The volume of the prism in the form of a trapezoid is given by:
 V = Ab * h
 Where,
 Ab: base area
 h: height
 We have then:
 Ab = (1/2) * (40 + 7) * (6)
 Ab = 141 m ^ 2
 Then, replacing we have:
 V = (141) * (3)
 V = 423 m ^ 3
 Answer:
 
The prism volume is given by:
 
V = 423 m ^ 3

Answer:

The answer to your question is SA =  2419.34 m²

Step-by-step explanation:

Data

a = 11.42 m

side = 11 m

height = 20 m

Formula

SA = 2B + PH

Process

1.- Calculate P

Perimeter = P

P = 7(11)

  = 77 m

2.- Calculate B

B = Pa/2

   = (77)(11.42)/2

   = 879.34/2

   = 439.67 m²

3.- Calculate 2B

2B = 2(439.67)

    = 879.34 m²

4.- Calculate PH

PH = (77)(20)

     = 1540 m²

5.- Calculate SA

SA = 879.34 + 1540

     = 2419.34 m²
