Question

If the length of one side of a cube is equal to 1cm, then its total surface area will be​

Answer 1

Answer:

• Its total surface area is 6 cm².

Step-by-step explanation:

Given that:

• The length of one side of a cube is 1 cm.

To Find:

• Total surface area of a cube.

Formula used:

• Total surface area of a cube = 6 × (side)²

Finding the total surface area of a cube:

⟶ Total surface area = 6 × (1 cm)²

⟶ Total surface area = 6 × 1 cm²

⟶ Total surface area = 6 cm²

More formula of a cube:

• Volume of a cube = (side)³
• Lateral/Curved surface area of a cube = 4 × (side)²
• Diagonal of a cube = √3 × (side)²

Answer 2

Given :-

• The length of one side of a cube = 1cm

To Find :-

• Total Surface Area

Solution :-

➞ T.S.A of Cube = 6 × (Side)²

➞ T.S.A of Cube = 6 × (1)²

➞ T.S.A of Cube = 6 × 1 × 1

➞ T.S.A of Cube = 6cm²

Thus Total Surface Area of Cube is 6cm²
