\[What~ is ~the ~volume ~of~ Hannah's ~paperweight?\] \[30 ~cm^{3}\] \[34~cm^{3}\] \[44~cm^{3}\] \[46~cm^{3}\]

OpenStudy (solomonzelman):

Can you find the height of the middle of the "-" (inside the/of the) \(\large\color{black}{ \bf H }\) ?

OpenStudy (solomonzelman):

I mena the height of the stick that connects the two havls of the H. If you want I can label your pic, I will need a bit to apload it.

OpenStudy (anonymous):

ok idc i just want the answer

OpenStudy (solomonzelman):

OpenStudy (solomonzelman):

labelled the middle you just need to apply the formula for Volmua for each piece. For each of the two \(\LARGE\color{black}{ \bf l }\), and for \(\small\color{black}{ \bf \square }\) in the middle.

OpenStudy (solomonzelman):

I love to disconnect in the middle of replying. This site has major issues, anyways, back to the prob. Apply the formula for volume: \(\large\color{black}{ \rm Volume =(height) \times(length)\times(width) }\)

OpenStudy (anonymous):

so (2x2) X (2x2) X (5x2)= 160

OpenStudy (solomonzelman):

Not exactly, lets do it together this time, okay?

OpenStudy (anonymous):

sure......-.^

OpenStudy (solomonzelman):

I couldn't put a 3D box in latex, sorry, so I will draw it...

OpenStudy (solomonzelman):

|dw:1418566999183:dw|can you find the volume of this?

OpenStudy (anonymous):

i think 20

OpenStudy (solomonzelman):

Yes, that is correct.

OpenStudy (solomonzelman):

And there are 2 of this pieces, yes? 9(each side of the H)

OpenStudy (solomonzelman):

So the volume of two of those is?

OpenStudy (anonymous):

40..

OpenStudy (solomonzelman):

Yup.

OpenStudy (solomonzelman):

Now we have a little piece in the middle left, it is:|dw:1418567188983:dw|what is the volume of it?
