Answer:
m = 8.0×10⁴ g
Explanation:
Given data:
Density of plastic = 0.80 g/cm³
Dimensions of plastic sheet = 1.0 m × 10.0 m ×1 cm
Mass of sheet = ?
Solution:
First of all we will convert the length and width into cm.
length = 10.0 ×100 = 1000 cm
width = 1.0 ×100 = 100 cm
Volume = 1000 cm × 100 cm × 1 cm
Volume = 100000 cm³
Mass of sheet:
D = m/v
0.80 g/cm³ = m / 100000 cm³
m = 0.80 g/cm³ × 100000 cm³
m = 80,000 g
m = 8.0×10⁴ g
