(1^3 + 2^3 + 3^3 + ... + 10^3) = x?	Choose the correct choice from the following answers: A) 360 B) 380 C) 420 D) 440 E) 450
We know that (1^3 + 2^3 + 3^3 + ... + n^3) =	1	2n(n + 1)   6   Putting n = 10, required sum = 1	x 10 x 10 x 21 = 2100/5   420   420
<result>C</result>
(1^3 + 2^3 + 3^3 + ... + 10^3) = x?
