What is the Volume of the Figure?

OpenStudy (anonymous):

OpenStudy (anonymous):

volume of the figure = volume of the cube + the volume of the square pyramid on top of it. volume of cube = side^3 volume of square pyramid = \(1\over3\)*area of base * height

OpenStudy (anonymous):

for the pyramid, |dw:1367078201125:dw|

OpenStudy (anonymous):

see, what do we get for the volume of the cube?

OpenStudy (anonymous):

27

OpenStudy (anonymous):

goo, now for the pyramid, we have its base. how about the height?

OpenStudy (anonymous):

2

OpenStudy (anonymous):

"2" is the slant height of the pyramid like I tried to show in the diagram above.

OpenStudy (anonymous):

I don't get it. What IS the height then!?

OpenStudy (anonymous):

height is the perpendicular distance of the peak from the base.|dw:1367078529480:dw|
