Volume of Basketball court = 3780 m^3

Mass = Volume x Density Density of ice is 916.7 kg/m^3 3780 x 916.7 = 3465126 kg

for 50% hollowness, mass is 1732563 kg

Density of frozen nitrogen: 1026.5 kg/m^3 Mass of ice trap: 1732563 kg Specific heat of nitrogen: 1040 j/kg Freezing point of nitrogen: -210 C Melting point of nitrogen: -196 C Dew point: 15.556 C

E = Q1 + Fusion + Q2 + Vaporization

(1732563 kg)(1040j/kg)(-196-(-210)) + (1732563 kg)(25702j/kg) + (1732563 kg)(1040j/kg)(15.55556-(-196)) + (1732563 kg)(199190j/kg) = 7.968611e+11 Joules/190.454389507648 Tons of TNT or Multi-City Block level
