Given:

Cube of sum of a number and 8

Find:

Expression

Computation:

Assume;

Given number is A

So,

Aum of A and 8 = A + 8

by cubing sum, we get

(A + 8)³

We know that;

(a + b)³ = a³ + b³ + 3a²b + 3ab²

So,

(A + 8)³ = A³ + 8³ + 3(A)²(8) + 3(A)(8²)

(A + 8)³ = A³ + 512 + 24A² + 3(A)(64)

(A + 8)³ = A³ + 512 + 24A² + 192A
