Answer 1

Answer:

when calculating pressure you must know that pressure is force/ Area

Explanation:

so here we have 20 kg we change it tobforce by saying

20×10=200N

then we need area of surface at which its lying and that is 80×23= 1840cm2

But remember

you must change it to m2

so 1m=100cm

1.84m

so 200/1.84
