Question

Without using your spring scale, estimate the order of magnitude of the mass of your calculator in grams from what you judge to be its size, using the fact that the density of water is 1 g/cmº.

Assume that the density of water is about the same as the density of your calculator.

1g
10^2 g
10^4 g
10^6 g​

Answer 1

91 grams is about 100 grams ... about 10² grams.

Explanation:

Its volume is (length) (width) (thick) = (13 x 7 x 1) = 91 cm³ and If its density is actually 1 g/cm³, then its mass is about 91 grams.
