Step-by-step explanation:
Total surface Area of a cube = 6a²
6a² = 2400cm²
a² = 2400cm²/6
a² = 400 cm²
a = 20 cm
Length of a side of a cube is 20 cm.
HAVE A NICE DAY!!!

Total surface area of cube =[tex] \rm{2400 {cm}^{2} }[/tex]
[tex]\rm{6 \times {side}^{2} }[/tex]=[tex] \rm{2400 {cm}^{2} }[/tex]
[tex] \rm {side}^{2} = \frac{{ \cancel{2400}cm}^{2}} { \cancel6} = 400 {cm}^{2} [/tex]
