Density / Pressure practice questions

1. 1A bar of chocolate measures 15cm x 10cm x 1cm and has a mass of 100g. What is the density ?
   [blank_start]100[blank_end] / ?
   Volume = [blank_start]15[blank_end] x [blank_start]10[blank_end] x [blank_start]1[blank_end] = [blank_start]150[blank_end]
   = [blank_start]100[blank_end] / [blank_start]150[blank_end]
   The density = [blank_start]0.6[blank_end]g/cm3

2. 2Find the mass of an object with a density of 4g/cm3 and volume 2cm3
   [blank_start]4[blank_end] x [blank_start]2[blank_end]
   = [blank_start]8[blank_end]g

3. 3Find the volume of a object with a density of 3.4g/cm3 and mass 23.8g
   [blank_start]23.8[blank_end] / [blank_start]3.4[blank_end]
   = [blank_start]7[blank_end]cm3

4. 4What is the pressure of an item with the force of 90N and an area of 5m2?
   [blank_start]90[blank_end] / [blank_start]5[blank_end]
   = [blank_start]18[blank_end]n/m2

   1. A90
   2. B5
   3. C18
5. 5What is the force of an item with a pressure of 43n/m2 and an area of 2m2 ?
   [blank_start]43[blank_end] x [blank_start]2[blank_end]
   = [blank_start]86[blank_end]N

   1. A43
   2. B2
   3. C86
6. 6What is the area of an item with a pressure of 270n/m2 and a force of 3240N ?
   [blank_start]3240[blank_end] / [blank_start]270[blank_end]
   = [blank_start]12[blank_end]m2

   1. A3240
   2. B270
   3. C12
