a) 2.3cm
b) 2.7cm
c) 2.6cm
d) none of these

Answer 1

$Let \: the \: edge \: of \: the \: cube = a \: cm$

$Volume \: of \: the \:cube = 19.683 \:cm^{3}$

$\implies a^{3} = 2.7 \: cm \times 2.7 \: cm \times 2.7 \: cm$

$\implies a^{3} = ( 2.7 \:cm )^{3}$

$\implies \green {a = 2.7 \:cm}$

Therefore.,

$Option \: \pink{ ( b ) } \: is \: correct .$
