(B) 64
(C) 125
(D) 225​

Answer 1

Step-by-step explanation:

27 is not a perfect cube

Answer 2

$\LARGE\textsf{\textcolor{red}{SOLUTION :-}}$

$\large\textsf{\colorbox{silver}{d) 225}}$

$\large\textsf{a) 27 = 3 × 3 × 3 = 3 ^ { 3 } }$

$\large\textsf{b) 64 = 4 × 4 × 4 = 4 ^ { 3} }$

$\large\textsf{c) 125 = 5 × 5 × 5 = 5 ^ { 3 } }$

$\LARGE\textsf{\textcolor{red}{But :-}}$

$\large\textsf{\colorbox{silver}{d) 225 = 15 × 15 = 15 ^ { 2} }}$

➠ $\large\textsf{So ' 225 ' is not a cube .} \\ \large\textsf{It's a square.}$
