What is the volume of the trapezoidal right prism? a. 846 m3 b. 720 m3 c. 423 m3 d. 56 m3

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
 
 The prism volume is given by:
 V = 423 m ^ 3

It is an outlier because idk sorry

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
