Find the volume of the figure below http://curriculum.kcdistancelearning.com/courses/GEOMx-HS-CA10/b/assessments/SA-SurfaceAreaandVolumeUnitExam/Geometry_9_Exam_FINAL_LT_060909_25q.jpg

OpenStudy (rulnick):

The triangular base has area (4 mi)(2 mi)/2 = 4 mi^2. This 4 mi^2 is multiplied by the length of the prism (7 mi) to get the volume.

OpenStudy (rulnick):

Get it? Volume = 4 mi^2 (7 mi) = 4(7) mi^3 = ...

OpenStudy (anonymous):

so the volume is 28?

OpenStudy (rulnick):

Yes, in mi^3 (miles cubed).

OpenStudy (anonymous):

ok.. the area of the triangle is what confused me.. thank you :)
