Answer: Lateral surface area of the cube is 676 cm .
Diagonal of the cube is 22.516 cm
Step-by-step explanation:
Total surface are of cube = 1014 cm²
Also,
total surface area of cube = 6a²
so,
→ 6a² = 1014 cm²
→ a² = 1014 / 6
→ a² = 169
→ a = √169
→ a = 13 cm [ ∴ a is the side of the cube ]
Now ,
Lateral surface area of of cube = 4a²
= 4 ( 13 )²
= 676 cm²
And,
Diagonal of the cube = √3 ( side )
= √3 ( 13 )
= 22.516 cm
