# The detailed solution for all the above-written question is as followsUsing the above pattern,$2^{3}-1^{3}=1+2\times 1\times 3$$3^{3}-2^{3}=1+3\times2\times 3$$4^{3}-3^{3}=1+4\times 3\times 3$find the value of the following.(ii) $12^{3}-11^{3}$

$12^{3}-11^{3} = 1 + 12\times11\times3 = 1 + 396 = 397$
