A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the density of lead.

Sure, here are the steps to calculate the density of the lead block:

Step 1: Calculate the volume of the block. The volume of a rectangular block is given by the formula length x width x height. So, the volume of the block is 4.50 cm x 5.20 cm x 6.00 cm = 140.4 cm³.

Step 2: Convert the weight of the block into kilograms, because the standard unit of density is kg/m³. 1 g is equal to 0.001 kg, so 1587 g = 1.587 kg.

Step 3: Convert the volume from cm³ to m³, because the standard unit of volume is m³. 1 cm³ is equal to 1e-6 m³, so 140.4 cm³ = 0.0001404 m³.

Step 4: Calculate the density. The density of an object is given by the formula mass/volume. So, the density of the block is 1.587 kg / 0.0001404 m³ = 11300 kg/m³.

So, the density of the lead block is approximately 11300 kg/m³.
