the measured quantities of a metal block are as follows:
length= 21.351 cm, width= 16.20 cm, height= 12.02 cm, mass= 8320 g
a- relate the length in centimeters to meters.
b- solve for the volume of the block. v=lwh
c- solve for the density of the block. D= m/v
a. 21.351 cm = 0.21351 m
b. Volume of the block = 21.351cm x 16.20cm x 12.02 cm = 4157.552124 cm^3
c. Density = 8320g / 4157.552124 cm^2 ≈ 2 g/cm^3
P.S. - if you wanted every dimension to be expressed in m ......16.2cm = .162m and 12.02 cm = .1202m
So...... the volume would be { .162 m x .1202 m x .21351m ] = 0.004157552124m^3
And the Density = 8320g / 0.004157552124m^3 ≈ 2 x 106 g / m^3
