Question

The total surface area of a cube with side 5 cm will be *
a) 120sqm
b) 150sqm
c) 155sqm
d) 125sqm

Answer 1

Answer:

b.150sqm

Step-by-step explanation:

the answer to ur question is 150

tsa= 6a^2

tsa=6×5×5

tsa=150sqm

Answer 2

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 )
