Answer 1

Answer:

$Nm {}^{2} {kg}^{ - 2} \\ \\ = (kgm {s}^{ - 2} )m {}^{2} {kg}^{ - 2} \\ \\ = {m}^{ 3} {s}^{ - 2} {kg}^{ - 1} \\ \\ = {(100cm)}^{3} .( \frac{30s}{30} ) {}^{ - 2} .(1000g) {}^{ - 1} \\ \\ = {(2 \times 50cm)}^{3} .( \frac{30s}{30} ) {}^{ - 2} .(2 \times 500g) {}^{ - 1} \\ \\ = {2}^{3} \times { \frac{1}{30 {}^{-2} } \times \frac{1}{2} } .{(50cm)}^{3} .( {30s} ) {}^{ - 2} .(500g) {}^{ - 1} \\ \\ = 3600 {(50cm)}^{3} .( {30s} ) {}^{ - 2} .(500g) {}^{ - 1} \\ \\ so \: answer \\ \\ = 6.67 \times 3600\: {(50cm)}^{3} .( {30s} ) {}^{ - 2} .(500g) {}^{ - 1}$
