Question

How would I find the volume of this figure? http://i.imgur.com/3yHcbib.jpg

Answer 1

get the area(by dividing the shape to pentagon and triangle) times height (area is constant along the height)
i can't understand the dotted line

Answer 2

Yeah neither can I @Catch.me but thanks anyway

Answer 3

Area of pentagon = area of ( ADE + ABD + BCD) = 2 * ADE + ABD

Area of ADE = 1/2 * base * height = 1/2 * 8 * 6.8
Area of ABD = 1/2 * 8 * 13

Volume = Area pf pentagon * 6

Answer 4

What happens to the dotted line? @aum

Answer 5

The dotted line on the left is just a perpendicular line from D to the side AE and that gives the height of the triangle ADE (= 6.8 cm).

Answer 6

Ok, thanks very much @aum

Answer 7

You are welcome.
