Find the measure of
SH
HM
TH
HR
TD
ER

Step-by-step explanation:

Centroid of a triangles is a point of intersection of it's medians.

Centroid divides the medians in the ratio of 2 : 1.

By this property of the centroid,

SH : HM = 2 : 1

Since, SM = 24,

SH =

     =

SH = 16

HM = SM - SH

      = 24 - 16

HM = 8

TH : DH = 2 : 1

Since, DH = = 4

          TD = 12

Therefore, TH = TD - DH

                         = 12 - 4

                  TH = 8

Since, EH = = 6

           ER = 18

Therefore, HR = ER - EH

                        = 18 - 6

                  HR = 12

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
