Question

if the lenth of a side of a cube is6 cm.find its surface area ​

Answer 1

Answer :-

• The surface area of cube is 216cm².

Step-by-step explanation :

To Find :-

• The surface area of cube

Solution :-

Given that,

• The length of a side of cube = 6cm

As we know that,

Surface area of cube = 6(a)² sq. units,

Where,

• a = side of cube

According the question,

=> Surface area = { 6(a)² } cm²

=> { 6 × ( 6 )² } cm²

=> ( 6 × 6 × 6 ) cm²

=> ( 6 × 36 ) cm²

=> 216 cm²

• The surface area of cube is 216cm².

Know more :-

• Total surface area of cube = 6(a)² sq. units
• Lateral surface area of cube = 4(a)² sq. units
• Volume of cube = a³ cubic units
• Diagonal of cube = a√3 units.

Here :-

• a = side of a cube.

Answer 2

Answer:

Surface Area of cube=216 $cm^{2}$

Step-by-step explanation:

Length of one side of cube = 6 cm

Area of one side of Cube = $Length of one side of cube^{2}$

                                           => $6^{2}$ $cm^{2}$

                                           => 6 × 6 $cm^{2}$

                                           => 36 $cm^{2}$

Surface area of cube = Area of one side of Cube*6

                                   => 36 $cm^{2}$ × 6

                                  => 216 $cm^{2}$
