This is Giancoli Answers
with Mr. Dychko.

00:00:03.900 --> 00:00:06.340
Density is mass divided by volume

00:00:06.340 --> 00:00:13.020
and we know the density of granite
in this table [10-1] on page 261

00:00:13.160 --> 00:00:17.800
and we can solve for mass by
multiplying both sides by <i>V</i>

00:00:18.100 --> 00:00:19.840
then switch the sides around

00:00:20.100 --> 00:00:23.120
and you end up with mass equals
density times volume.

00:00:23.200 --> 00:00:26.160
So that's 2.7 times 10 to the 3
kilograms per cubic meter—

00:00:26.160 --> 00:00:27.340
density of granite—

00:00:27.380 --> 00:00:30.280
times about 1 times 10 to the 8
cubic meters—

00:00:30.280 --> 00:00:34.560
volume of this El Capitan rock
in Yosemite park—

00:00:34.660 --> 00:00:37.960
and you get 3 times 10 to the 11 kilograms.
