Question

Find the cubes of:
(i) −11
(ii) −12
(iii) −21

Answer 1

(i)
Cube of $-$11 is given as:
${\left(-11\right)}^3=-11\times -11\times -11=-1331$
Thus, the cube of 11 is ($-$1331).

(ii)
Cube of $-$12 is given as:
${\left(-12\right)}^3=-12\times -12\times -12=-1728$

Thus, the cube of $-$12 is ($-$1728).

(iii)
Cube of $-$21 is given as:
${\left(-21\right)}^3=-21\times -21\times -21=-9261$

Thus, the cube of $-$21 is ($-$9261).
