Surface area of a cube = 6 × (side)²
=6×32=6×9=54 cm²
0 (since the square of a prime number is not prime)
A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself.
The square of a prime number is not prime because it has at least three divisors: 1, the prime number, and the square itself.
0.005 × 10,000 = 50 So the question becomes: 50 is what percent of 50?
50/50×100=100%
An equation of the form ax² + bx + c = 0 is called a quadratic equation.
Here, it has no x-term, but still fits that form.
Let original number = 100
Increase 30% ⇒ 130
Decrease 10% ⇒ 130 - 13 = 117
Net change = 117 - 100 = 17% increase
In Flutter, the Scaffold() widget is typically used within the build() method of a StatefulWidget or StatelessWidget.
More specifically, it serves as the root widget for most screens in a Flutter application, providing the basic layout structure for Material Design.
72 marks = 80% of total marks
Let total marks = x
So, 0.8x = 72 ⇒ x = 72 ÷ 0.8 = 90
"Sitara Chamakna" means "to shine like a star," symbolizing success, achievement, or rising to prominence.
1 + 2 + 3 + ... + n = 15
This is an arithmetic series. Use the formula:
n(n + 1)/2 = 15
→ Multiply both sides by 2:
n(n + 1) = 30
Try n = 5:
5(6) = 30
So, n = 5
Now calculate:
1³ + 2³ + 3³ + ... + n³
Use formula:
[n(n + 1)/2]² = [5×6/2]² = (15)² = 225
In "Goodbye, Mr. Chips" by James Hilton, Chips saw the great exhibition as a toddling child wobbling.
