Let's suppose that it takes three hours to bake a pie. Then how many could we bake in 60 hrs??

Answer....20 pies......and everyone knows that 20 "pi's" ≈ 62.832

So....there's "x".......(more or less)

which is the value of this radical sqrt (3 * 5 ^ ^

√(3*5) = √(15)

Esto es todo lo que podemos hacer. ¿Alguno de su problema de conseguir "cortado?"

(This is all we can do. Did some of your problem get "cut off??")

Who dares to question rosala??  .... How about  a little "fire," Alan (and reinout)...???

After looking at this again, let's analyze it to see if I blew a fuse (which is always a faint possibility)....I know that a tetrahedron can be put in a cube (as the picture indicates) and that it can be oriented in such a way as to produce a tetrahedron that is equal to (1/3) of the cube's volume, but I'm having second thoughts as to whether or not THIS pariticular orientation produces such a thing.

Let's call the side length of the cube, s. Notice that every edge length appears to be just √(s² + s²) = s√2. And the "formula" for the volume of a tetrahedron with edge length "a" is just

(a)³/(6√2)    ....so we have.....

(s√2)³/(6√2)  = [(s³)2√2] / [6√2] = 2s³/6 =

........s³/3 ..........

Mmmmm.........interesting!!

Did I make a mistake somewhere along the line??

HAHAHA!!!!!.....I love that one, Melody!!!

But, still.......THE GREAT AND POWERFUL OZ HAS SPOKEN!!!! .....Now, bring me the broomstick of the Wicked Witch of the West!!!.....Go!!!   .....Go!!!

Quiet, whippersnapper!!! Things are what we say they are !!!

I'll get you, my pretty...and your little dog, too!!

See if you can answer your own question....are 48 hrs. 2 days??

How could you find out??  If 1 day = 24 hrs., what would you need to do to find out how many hrs. are in 2 days??

Think about it a little........

No such thing.......whatever you think might be the highest....I can always add 1 to it !!!

There ARE some well-known "Large" numbers, however....here's one.....

I'm assuming you want to find the volume of a tetrahedron inscribed in a cube....I don't know much about this, but there is a way it can be done.....(see below)....the volume of this is just 1/3 the volume of the cube = s^3/3  where s is the side of the cube....

There may be other answerers who could give you more help, but if not, here's a page that will probably tell you more.....
