Question 157837: My daughter is having trouble solving an equation in her grade 9 science class.
This is the question:A piece of wood has the density of 430kg/m cubed, what is the mass of 50m cubed of this wood?
I do not have a text book it is on a printed piece of paper.
I hope you can help.
She just needs a little direction, I don't want the answer, I would like her to do on her own.
I can't remember how to calculate this.
Thank you for your time.

---------------
The wood weighs 430kg/m^3. That means 1 m^3 weighs 430 kg (kilograms).
yhere are 50 meters^3 of it, so it weighs 50 times the 430 kg/m.
That's 430*50 = 21,500 kilograms.
-----------------------
That's over 20 tons, so don't get under it.
