Answer:
1.4 g/cm³
Step-by-step explanation:
1. Calculate the volume of the block
V = lwh
Data:
l = 150 cm
w = 0.20 m
h = 6.0 mm
(a) Convert all units to a common base
w = 0.20 m × (100 cm/1 m)
w = 20 cm
h = 6.0 mm × (1 cm/10 mm)
h = 0.6 cm
Calculation:
V = lwh
V = 150 × 20 × 0.60
V = 1800 cm³
2. Calculate the density
Density = mass/volume
Data:
m = 2.5 kg
Calculation:
m = 2.5 kg Convert to grams
m = 2.5 kg × (1000 g/1 kg)
m = 2500 g
Density = 2500 g/1800 cm³
Density = 1.4 g/cm³
