Question #2217

Morgan has measured the dimensions of a block of lead. it is 8.50cm x 5.50cm x 20.0mm what is the mass in kilograms of this block of lead is 1.25 x 10 exponent 4 mg/cm exponent 3?

Expert's answer

The volume of the book is V=abc = 8.5 [cm] x 5.5[cm] x 2.0 [cm] = 93.5 cm

1.25 x 10

The mass of the book is m = ρ V = 1.25 x 10

^{3}.1.25 x 10

^{4}mg/cm^{3}= 1.25 x 10^{-2 }kg/cm^{3}.The mass of the book is m = ρ V = 1.25 x 10

^{-2}* 93.5 = 1.17 kg.Need a fast expert's response?
