Question

What is the volume of the trapezoidal right prism?



A.
846 m3

B.
720 m3

C.
423 m3

D.
56 m3

Answer 1

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 2

(40+7) / 2 = 23.5

23.5 x 3 = 70.5

70.5 x 6 = 423 m3

Answer is C
