The volume of a cube is given by:

V = side³

= 5³

= 5 × 5 × 5

= 125 cm³

Explanation

Given:

Increment in number = 20% of the number

Decrement in number = 20% of the new number

Concept used:

Net increase or decrease percent = {(Original number or Final number) - (Final number or original number) ÷ Original number} × 100

Calculation:

Let the original number be 100

When the number is increased by 20%

New Number = 100 + 20% of 100

⇒ 100 + 20

⇒ 120

Now, the number is decreased by 20%

Final number = New number – 20% of new number

⇒ 120 – 20% of 120

⇒ 120 – 24

⇒ 96

∴ Net Decrease in percentage = { (100 – 96) / 100} × 100

⇒ {4/100} × 100

⇒ 4%

∴ The net decrease percentage is 4%

Explanation

The sum of the exterior angles of any polygon is always 360 degrees. 

As for the interior angles, the sum of all the interior angles in a polygon is equal to: (n-2) x 180

Explanation

Al'Khwarizmi was an Islamic mathematician who wrote on Hindu-Arabic numerals.

The word algorithm derives from his name.

He wrote the first systematic book on Algebra, Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala.

Explanation

80 percent of 700 is 560.

80 percent *700

= (80/100)*700

= (80*700)/100

= 56000/100 = 560

Explanation

3/100 x = 60

3x=60×100

3X=6000

X = 6000÷3

X = 2000.

Explanation

To find 25% of 150, multiply 150 by 0.25:

150 × 0.25 = 37.5.

Therefore, 37.5 is 25% of 150.
