125

Number
$125$ (one hundred and twenty-five) is:


 * $5^3$


 * The $5$th cube number after $1$, $8$, $27$, $64$:
 * $125 = 5 \times 5 \times 5$


 * The $3$rd power of $5$ after $(1)$, $5$, $25$:
 * $125 = 5^3$


 * The $13$th trimorphic number after $1$, $4$, $5$, $6$, $9$, $24$, $25$, $49$, $51$, $75$, $76$, $99$:
 * $125^3 = 1 \, 953 \, \mathbf {125}$


 * The $17$th powerful number after $1$, $4$, $8$, $9$, $16$, $25$, $27$, $32$, $36$, $49$, $64$, $72$, $81$, $100$, $108$, $121$


 * The length of the shortest face diagonal of the smallest cuboid whose edges and the diagonals of whose faces are all integers:
 * The lengths of the edges are $44$, $117$, $240$
 * The lengths of the diagonals of the faces are $125$, $244$, $267$.


 * The $10$th integer after $7$, $13$, $19$, $35$, $38$, $41$, $57$, $65$, $70$ the decimal representation of whose square can be split into two parts which are each themselves square:
 * $125^2 = 15 \, 625$; $1 = 1^2$, $5625 = 75^2$


 * The $4$th positive integer after $50$, $65$, $85$, and first cube, which can be expressed as the sum of two square numbers in two or more different ways:
 * $125 = 11^2 + 2^2 = 10^2 + 5^2 = 5^3$
