    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
