Given that : Side of a cube is 5cm
Need to find : The total surface area of that cube
⠀━━━━━━━━━━━━━━━━━━━
❍ To calculate the total surface area of the cube we must know that ::
- TSA = 6s²
Where,
- TSA denotes total surface area
- s denotes side of the cube
T H E R E F O R E,
=> TSA = [ 6 × 5² ]
=> TSA = 6[ 5 × 5 ]
=> TSA = 6[ 25 ]
=> TSA = 6 × 25
=> TSA = 150cm²
⠀━━━━━━━━━━━━━━━━━━━
- Henceforth, the total surface area of the cube is 150cm²
More formulas :
★ Total Surface area = 6 × ( Side )²
★ Lateral Surface area = 4 × ( Side )²
★ Diagonal of cube = 3√side
★ Volume of cube = ( Side )³
★ Perimeter of cube = 12 × ( Side )
