Question

A block of lead has dimension of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g waht type of material is the block made of?

Answer 1

The density of lead is 11.30 g/cm^3

Given the following data :

• Length = 4.50 cm
• Width = 5.20 cm
• Height = 6.00 cm
• Mass of lead = 1587 g

To find the density of lead :

First of all, we would determine the volume of the block of lead by using the formula :

Volume = length × width × height

Substituting the values into the formula, we have;

Volume = 4.50 * 5.20 * 6.00

Volume = 140.4 cm^3

Next, we find the density of lead;

Density = \frac{Mass}{Volume}

Substituting the values into the formula, we have;

Density = \frac{1587}{140.4}

Density = 11.30 g/cm^3

Therefore, the density of lead is 11.30 g/cm^3
