it is a difficult picture to read....so it is a pyramid w a triangle base?

superdavesuper · Answer

Hahahaa no, the picture uploaded just fine but its still difficult to read lol

OK - do u know how to calculate the volume of a pyramid; given its base area and height?

superdavesuper · Answer

correct on first two but the third.....need one minor change....find the eqn for volume of pyramid plz? u are soooooo very close ;)

superdavesuper · Answer

nope but volume of pyramid is not equal to base area x height...its smaller...

superdavesuper · Answer

read ur note on this plz but volume of pyramid = base area x height / 3 :) u missed the /3 part

superdavesuper · Answer

no, absolutely nothing wrong about asking n plz dont feel dumb at all. i apologize if i made u feel that way :(

OK base area=24 n height=3, u have found those already but when calculating the volume, it should be 24*3/3  so the answer should be 24 instead of 72. Are we good on this? :)

superdavesuper · Answer

Ok weird the way they arrange the Qs....should go w the last question first n that would be 8/18 = 4/9

superdavesuper · Answer

oooooo nevermind.....plz ignore my last post....i mis-read :(

superdavesuper · Answer

so A1/AII = 8/18 = 4/9 that is correct

superdavesuper · Answer

nope they cancel each other out

superdavesuper · Answer

then the Q already tells u the second ans is a/b so just sqrt 4/9 u get 2/3

superdavesuper · Answer

last a^3/b^3....u can figure it out on ur own :)

superdavesuper · Answer

hmmm....nope....

superdavesuper · Answer
