The density of a certain type of plastic is 0.80g/cm. If a sheet of this plastic is 10.0 m long, 1.0 m wide, and 1 cm thick, what is its mass? Enter your answer in scientific notation.

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

i'm pretty sure its b i might be wrong though!
