Given the statement:
A sample of iron has the dimension of 2cm x 3cm x2cm.
Determine the density if the mass is 94 g.
Formula for density:
d = m/v
d = density
m = mass
v = volume
Solution:
Solve first the volume by multiplying the values of the dimensions.
Volume = 2cm x 3cm x 2cm
Volume = 12 cm^3
Substitute the values of mass and volume to the formula for density.
d = m/v
d = 94 g/12cm^3
d = 7.83 g/cm^3
Final answer:
d = 7.83 g/cm^3
