Answer:
The mass of the block made of lead = 255.6 grams
Step-by-step explanation:
Step 1: Data given
Density of lead = 11.36 g/cm³
length of the block = 5 cm, 1.5 cm and 3 cm
Step 2: Calculate the volume of the block
Volume = length 1 * length 2 * length 3
Volume = 5cm * 1.5 cm * 3 cm
Volume = 22.5 cm³
Step 3: Calculate mass
Mass of the lead block = density of lead * volume
Mass of the lead block = 11.36 g/cm³ * 22.5cm³
Mass of the lead block = 255.6 grams
The mass of the block made of lead = 255.6 grams
