Answer 1

Answer :

• Volume = 166.375 cm²
• Total surface area = 181.5 cm²
• Lateral surface area = 121 cm
• Diagonal = 9.515 cm

Step-by-step explanation :

To Find,

• The volume
• The total surface area
• The lateral surface area
• Diagonal

Solution,

Given that,

• Edge of the cube = 5.5 cm

_______________________

★ Volume of the cube

Formula :- Volume of cube = a³

∴ Volume of the cube

» ( 5.5 )³

» 166.375 cm³

______________________

★ Total surface area

Formula :- ( 6a² )

∴ Total surface area of cube

» 6 × 5.5²

» 6 × 30.25

» 181.5 cm²

______________________

★ Lateral surface area

Formula :- ( 4a² )

∴ Lateral surface area of cube

» 4 × 5.5²

» 4 × 30.25

» 121 cm²

______________________

★ Diagonal

Formula :- a√3

∴ Diagonal of cube

» 5.5 × 1.73

» 9.515 cm
