Answer 1

find the area of the trapezoidal face and then multiply by the height of the prism

Answer 2

your saying this because B is not right I am guessing

Answer 3

I have no idea... I didn't do the calculation....

but the method I posted is what you need to do

Answer 4

I did

Answer 5

well am I correct

Answer 6

Answer 9

\(V = \dfrac{1}{2}h(a + b)l\)

\(V = \dfrac{1}{2}(7)(20 + 8)(2)\)

\(V = \dfrac{1}{2}(7)(28)(2)\)

\(V = (3.5)(28)(2)\)

\(V = (98)(2)\)

\(V = 196\)
