Explanation

Given:

Height = 0.56 m = 56 cm (since 1 m = 100 cm)

Width = 21 cm

Volume = 51744 cubic cm

Let's denote the length as L cm. The formula for volume is:

Volume = Length * Width * Height

51744 = L * 21 * 56

51744 = L * 1176

L = 51744 / 1176

L = 44 cm

To convert length to meters:

L = 44 cm = 0.44 m

Explanation

The incenter is the point where the three angle bisectors of a triangle meet.

It is the center of the incircle, the circle that touches all three sides of the triangle.

tan 45° = 1 in trigonometry.

Explanation

This looks like an arithmetic sequence problem.
If the first term $a = 3$ and last term $l = 18$, and there are 4 numbers in between, the total terms $n=6$ (3 + 4 + 18).

The terms:
$a_1 = 3$
$a_6 = 18$
Number of terms $n = 6$

Common difference $d = frac{18 - 3}{6 - 1} = frac{15}{5} = 3$

The 3rd middle number is the 4th term:
$a_4=a_1+3d=3+3\times 3=12$

Explanation

The mean is a measure of location or measure of central tendency of the distribution on its scale.

Explanation

Length of the frame = 12 cm
Width of the frame = 8 cm

Perimeter of a rectangle = 2 × (length + width)

So, the perimeter $P$ is:
$P = 2 times (12 text{ cm} + 8 text{ cm})$
$P=2\times 20\text{ cm}$
$P = 40 text{ cm}$

Now, convert the perimeter from centimeters to meters (since the cost of ribbon is given per meter):
$\text{Perimeter in meters}<font\; color="\#0000ff">=</font>\frac{}{}$40 cm100text{Perimeter in meters} = frac{40 text{ cm}}{100}
$text{Perimeter in meters} = 0.4 text{ m}$

Next, calculate the total cost of the ribbon:
Cost of 1 meter of ribbon = Rs 5

Total cost of ribbon = Cost per meter × Length in meters
$text{Total cost} = 5 times 0.4$
$\text{Total cost}=Rs2$

Therefore, the total cost of the ribbon Nadia needs is Rs 20.

Explanation

Perimeter formula for a rectangle: 2 × (Length + Width)

2 × (210 + 118) = 2 × 328 = 656 cm

Explanation

To find the perimeter of a rectangle, use the formula:

Perimeter = 2 × (Length + Width)

Given:

Length (L) = 4 cm

Width (W) = 3.4 cm

Calculate:

Perimeter = 2 × (4 + 3.4)

= 2 × 7.4

= 14.8 cm

Explanation

The surface area of a cuboid is given by:

2(lb + bh + hl)

Where l = 12cm, b = 8cm, h = 6cm

Surface area = 2(12_8 + 8_6 + 6*12)

= 2(96 + 48 + 72)

= 2(216)

= 432cm²
