Answer :-
Answer :- 11.258 cm
Here, side,a = 6.5 cm
Volume = a³
= (6.5 cm)³
= 6.5 cm × 6.5 cm × 6.5 cm
= 274.625 cm³
Lateral surface area = 4a²
= 4 × 6.5 cm × 6.5 cm
= 169 cm²
Total surface area = 6a²
= 6 × 6.5 cm ×6.5 cm
= 253.5 cm²
Diagonal of cube = √3 × a
= √3 × 6.5 cm
=1.732 × 6.5 cm ( the value of √3 is taken to as 1.732 )
= 11.258 cm
