Find the volume of the 3-D solid shown below:
8 in
6 in
13 in
278 in3
293 in
315 in3
355 in3

Check the picture below.

so is really just a thick trapezoid, or namely a trapezoidal prism 5 inches thick.

so if we just get the area of the trapezoidal face and multiply by the thickness, we'd get it's volume
