1. The problem statement, all variables and given/known data A wooden block of mass 1.2 kg with dimensions 20cm x 10 cm x 10cm . It's resting on the surface PQYX (with base area 10cm x 10 cm , the vertical side would be 20cm in this case).What is the work done to enable it to rest on surface PQYX 2. Relevant equations 3. The attempt at a solution On first thought , work done is simply the gain in potential energy , mgh=(1.2)(10)(0.2)=2.4 J but that isn't the answer .
