When water freezes, its density drops from 1.00g/cm3 to 0.92 g/cm3 find the mass in grams of an ice cube 1 meter on edge 1m = 100cm

Step-by-step explanation:

Assuming that the ice cube is a perfect cube, an ice cube with sides of 1 m = 100 cm has volume:

V = s^3 = (100 cm)^3 = 1,000,000 cm^3.

Then, since the density of ice is 0.92 g/cm^3, we have:

(1,000,000 cm^2) * (0.92 g)/(1 cm^3) = 920,000 g of ice.

I hope this helps!

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
