Question

What is the volume of the trapezoidal right prism?

A.
846 m3

B.
720 m3

C.
423 m3

D.
56 m3

Answer 1

(40+7) / 2 = 23.5

23.5 x 3 = 70.5

70.5 x 6 = 423 m3

Answer is C

Answer 2

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
