Answer:1 pa

explanation :

pressure = volume ÷ mass

50×30×20 = 30000 = 30m

30m ÷ 30kg = 1

units for pressure = pascals

so pressure = 1 pa

Answer:0.2pascal

Explanation:when the box is on the ground,

Then Force= weight

F=mg, which is

F= 30*10=300N

and also the area

Area= 50*30=1500cm^2

Therefore

Pressure =Force / Area

Pressure = 300/1500 = 3/15 =0.2pascal
