OpenStudy (cali):

sorry i hope you can understand it... i tried my best to draw it..

OpenStudy (anonymous):

is this the picture that yu see.

OpenStudy (cali):

this is a hint it gives me but i dont understand...---- > to add together the volume of a bottom prism: V=lwh and the volume of top pyramid is V=Bh/3

OpenStudy (anonymous):

ok think bottom prism which is the rectangle . its V=lwh so thats v=2.5*3*2 so that equals 15 as the volume,. then you move to the top which is a triangle . thats V=bh1/3 n thats V=2.5*1.5*1/3 n that equals 1.25 as the volume

OpenStudy (cali):

where did you get the 1/3 from?..

OpenStudy (anonymous):

volume of a triangle is v=bh1/3

OpenStudy (cali):

o alright thanks! i thought it was bh1/2.

OpenStudy (cali):

thank you so much this really helped me! :)

OpenStudy (anonymous):

my sister said to put it this way For the dolls house, it is made up of 2 regular shapes. The volume of the bottom half is easy enough. BOTTOM PART = 2.5*3*2= 15cubic feet. For the top part, the rule is that anything pyramid shaped or cone shaped will be: AREA OF BASE * HEIGHT * 1/3 For this case it will be; (2.5*3)*1.5/3=3.75 cubic feet TOTAL VOLUME = 15 +3.75 = 18.75 cubic feet.

OpenStudy (cali):

yes i love how you explain this soo well thanks you soomuch!

OpenStudy (anonymous):
