Question 1142210: Packing foam weighs 0.4 KG per cubic meter. If that box measures 2m by 3m by 5m Is filled with packing foam, How much foam will be used?
A)4
B) 6
C) 10
D) 12
I convert 0.4 kg to m = 400
Then, 2X3X5= 30
400/30 =13.3
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! packing foam weighs .4 kilograms per cubic meter.
the box measures 2 * 3 * = 30 cubic meters.
the amount of foam that can be packed in the box is .4 * 30 = 12 kilograms.
from the web:
---------------------------
To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.
-------------------------------
the density of the foam is .4 kilograms per cubic meter of volume.
to find out how many kilograms of foam will fit in the box, the formula becomes (.4 * kg) / (1 * cm) * (30 * cm) = .4 * 30 = 12 kg.
in this formula, kg = 1 kilogram and cm = 1 cubic meter.
the cm in the numerator cancels out the cm in the denominator and you are left with 12 kilograms.
you can fit 12 kilograms of foam in the box.
