Answer 3

I got 78 but not sure on the units

Answer 4

each dimension is cm

cm * cm * cm = cm^3 as your units

Answer 5

also i got 78 using a calc could you explain to me how it would be 78? like sig figs?

Answer 6

plugging in the digits, you get 77.616 exactly. this # has 5 sig figs.

since each dimensions only has two sig figs, the answer must only has two sig figs so we round to 78

Answer 7

if you need some help identifying sig figs I wrote a tutorial a while ago about it:

- identify the first nonzero digit and the last nonzero digit, and include all the digits in between, inclusive
ex. 00105.4 has only 4 significant digits (the leading zero's do not count)
- leading zero's are not significant
- trailing zero's are not significant in a whole # but are significant in decimal #'s
ex. 10540 only has 4 significant digits (the trailing zero does not count) but 1054.0 has 5 significant digits (the trailing zero after a decimal pt. does count). 1050 has 3 significant figures while 1050. has 4 (notice the decimal point after the last 0)

Answer 8

okay so if I were to want one sig fig and I had the number 4.6. I would stick to 5?

Answer 9

yes
