Help please!!!!

thomaster (thomaster):

volume = lenght x height x width

OpenStudy (e.mccormick):

For the surfac area, find the area of each side and add them together. For the volume, thomaster jsut posted it.

OpenStudy (anonymous):

So 512?

OpenStudy (e.mccormick):

512 is the volume.

thomaster (thomaster):

8 * 8 * 8 = 512 in^3 surface is 8*8 = 64 in^2

OpenStudy (mertsj):

What is the area of the bottom?

OpenStudy (e.mccormick):

For SA, there is one advantage with a cube. All 6 sides are the same.

OpenStudy (anonymous):

so 512 x 3?

thomaster (thomaster):

nooooo 64 times 6

OpenStudy (anonymous):

I get 384

thomaster (thomaster):

there are 6 sides of 64 inche square

OpenStudy (anonymous):

I get 384

OpenStudy (anonymous):

So 512 subtract 384?

OpenStudy (e.mccormick):

6 sides, each side has 8 by 8 dimensions. As Mertsj points out, sort of indirectly, you can start with one side like the bottom, find it, and then I am betting his next step would have been to have you multiply that by 6.

thomaster (thomaster):

the surface area has nothing to do with the volume

OpenStudy (anonymous):

I need the surface area

thomaster (thomaster):

surface area is 384 inch square Volume is 512 inch^3

OpenStudy (e.mccormick):

384 is the SA. That is the answer. This is actually two question and you need to do the math seperatly for each.
