Answer:
4.67 kg
Explanation:
Given data
- Dimensions of the lead sheet: 75.0 cm by 55.0 cm by 0.10 cm
- Density of lead: 11.3 g/cm³
Step 1: Calculate the volume of the sheet
The volume of the sheet is equal to the product of its dimensions.
Step 2: Calculate the mass of the sheet
The density (ρ) is equal to the mass divided by the volume.
