A rectangular block of iron was found to be 19.00 cm wide, 0.31500 m high, and 720.026 mm deep. Calculate the volume of this box in units of cm³. Be sure to express your answer to the correct number of significant figures.
The density of an unknown metal is 1.057 g/mL. To determine the mass of this metal the metal was placed in a graduated cylinder filled with water. The initial height of the water was 20.00 mL and after the metal was placed in the cylinder the water rose to 26.17 mL. What is the mass of this metal?
You are trying to determine the density of a piece of metal. You use a balance and find that the mass of the piece of metal is 56.72 g. To determine the volume of the metal, you fill a graduated cylinder to 31.0 mL and then drop the piece of metal into the graduated cylinder. The final volume is 38.9 mL. What is the density of the piece of metal?
A 100.0 mL graduated cylinder was used to measure the volume of water. The initial volume of the water was determined to be 50.0 mL. You drop a 96.51 g metal coin into the water.
