How do I work out Density??
Sorry I have just had a total blank and cannot remember how on earth to work out Denstiy!!
The question I have been given is...
The area of the cross section of the prisim is 60cm² The length of the prisim is 24cm.
The prisim is made from wood. The prisim has a mass of 648g. Work out the density of the wood.
Thank you!

Density is mass per unit volume, so you need to know the volume of the prism which is given by
60x24 = 1440cm³
the density is then
648/1440 = 0.45 gcm-¹
