have a have begun but we don't know our area or volume so how do we find these well to start you have to find the area we have the equation for area next to that or heptagon which is base times height / 15 times the number of sides so to start we have to find our base which is six inches now we have to find our Heights our height is 6.5 inches now we divide their bio point five we know times that entire equation by the number of sides we have because this is a heptagon it is seven our area is 78 inches squared now to find the value our value to find the volume you take the bottom equation area times debt but what is how deep is this heptagon if you look towards the bottom of your screen you will see we have a side view our side view happens to be four inches so now we take the area 78 inches squared and times it by four when we do this we get our value of three hundred and twelve inches cubed remember when you're finding needs to always cube the area tour to always give the volume and square the area you have now learned how to find the area and volume of a have begun
