Question

find the edje of a cube whose TSA is 432cm square

Answer 1

Correct Question :

Find the edge of a cube whose Total surface area is 432cm².

Answer :

• The edge of cube is 6√2cm.

Step-by-step explanation ::

To Find :-

• The edge of a cube

Solution :-

Given that,

• The total surface area of cube is 432cm²

According the question,

As we know that,

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

Where,

• a = side of cube

➠ 6a² = 432

➠ a² = 432 / 6

➠ a² = 144 / 2

➠ a² = 72

➠ a = √ 72

➠ a = √ ( 36 × 2 )

➠ a = 6√2

The edge of cube is 6√2cm.

More Information

Some more information related to the surface area & volume of cube :-

Here, a = side of cube

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

Answer 2

Step-by-step explanation:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion
