Answer 2

Calculating the Weight of the Block

To calculate the weight of the block, we can use the formula:

Weight = Volume × Density

First, we need to calculate the volume of the block using the given dimensions: 5 cm, 12 cm, and 65 cm.

Calculating the Volume

The volume of the block can be calculated using the formula:

Volume = Length × Width × Height

Substituting the given dimensions: Volume = 5 cm × 12 cm × 65 cm

Now, we can calculate the volume.

Volume Calculation

Volume = 5 cm × 12 cm × 65 cm Volume = 3900 cubic centimeters

Now that we have the volume, we need to determine the density of lead, as the block is made of lead.

Determining the Density of Lead

The density of lead is approximately 11.34 grams per cubic centimeter.

Weight Calculation

Using the formula Weight = Volume × Density and substituting the values: Weight = 3900 cubic centimeters × 11.34 grams per cubic centimeter Weight ≈ 44,286 grams

So, the weight of the lead block is approximately 44,286 grams.
