Question

average depth of snow is 2.5m
top 50cm has density of 0.15gcm^-3, middle 100cm has a density of 0.2gcm^-3 and bottom layer 100 cm has density of 0.25gcm^-3
question what is total mass of snow in 1m^2
can anyone help me figure this out I am thinking it is pretty simple but

Answer 1

Find the volume of each layer:
(1 m)(1 m)(50 cm)
(1 m)(1 m)(100 cm)
(1 m)(1 m)(100 cm)
Remember to convert all units to cm to get the volumes in cm^3. Then multiply each volume by its density to get a mass, and then add all masses together.

Answer 2

do you know what gcm^-3 is?

Answer 3

it's the same as g/cm^3 or gram per cubic centimeter

Answer 4

When you multiply gcm^-3 by cm^3 you get g, so if you multiply the density of each layer of snow in gcm^-3 by its volume in cm^3 you'll get the mass of that layer.
