PLZ GIVE COMPLETE SOLUTION FOR THESE 3 questions plz

1)pressure =241 kpa

to covert kpa to pound square inch(psi),multiply kpa value by0.14503773773020923

pressurep=241*0.1450773773020923=34.9541psi

2)VOLUME=LBH=1.2*0.75*0.6=5.4m^3=5.4*10^6cm3

densiy=mass/volume

mass=vol*density of ice

we know density of ice=0.9167g/cm^3

mass=5.4*10^6(0.9167)

weight=mass*specific gravity=4.95*0.9*10^6=4.4*10^6
