A rectangular marble block has dimensions 1 m by 1 m by 5 m and weighs 125 000 N.
The marble block is stored with the long side resting on the ground, as in diagram 1.
What is the change in the pressure on the ground due to the block when the block is stored as in diagram 2 rather than diagram 1?
1 )
a decrease of 25 000 N / m$^2$
an increase of 100 000 N / m$^2$
3 )
an increase of 125 000 N / m$^2$
4 )
no change
