how can i slice a gold bar into 7 pieces cutting only twice?

Answer 1

Fold it in half and cut an "X" shape from corner to corner.

Answer 2

First you melt the gold. Then you reform it into four equal parts. Then you cut one of the equal parts into four parts by cutting twice from corner to corner.

Just kidding.

Maybe,

you can cut the gold bar into three pieces, one 1/7, one 2/7 and one 4/7. Then you can get the seven differenct values you may be seeking.

Let a=1/7, b=2/7, c=4/7.

Then by manipulating the three pieces, you can get:

1 a
2 b
3 a and b
4 c
5 a and c
6 b and c
7 a and b and c

Answer 3

By cutting twice you can make maximum 4 pieces . For 7 Minimum 3 cuts

Answer 4

You can't. You can only slice it into 4 pieces, or if it's shaped like bubble wrap, you can cut it into a million little pieces cutting only twice.

Answer 5

Hmm, I'm not sure you're asking the right riddle. I've heard this one before, but it goes something like this...

You employ someone to work for you for seven days. To pay your employee, you have one bar of gold which is has seven segments. Your employee needs to be paid for their days work at the end of each day.

You may only cut the gold bar twice. How do you pay your employee?

Are you sure this isn't what you're asking?

Answer 6

are these cuts straight lines through a rectangular prism shaped gold bar? if they are wavy i could do it. :)

Answer 7

cut a sine wave shaped first cut and then bisect it with another cut. Simple.

Answer 8

Get two knives and glue them together xD

Answer 9

You can't, unless it's shaped funny.
