The volume of a cuboid is 972m3. If its length and breadth be 16m and 13.5 respectively,find its height.

Answer»

ANSWER:

Hint-

The volume of a cuboid is given by, V = LBH (L=length, B = breadth, H=height).

Here V = 972 CUBIC m.

L = 16m

B = 13.5m

H = ?

Just EVALUATE the value of V = LBH, you will get the desired result.

972 = 16 * 13.5 * H

fraction numerator 972 over DENOMINATOR 16 cross times 13.5 end fraction equals straight H

24.	A wire is bent to form a square of side 11cm if this wire is re should to form a rectangle of length 16 cm find the breadth of rectangle and area of rectangle
Answer» Required ANSWER:- A simple logic we have to apply here. We know that the same wire was used to make both the SHAPES. It means the length of the wire is same for both square and rectangle. Hence the perimeter of square = perimeter of rectangle $.$ Now, We already have the side of the square, So we can find the perimeter of square because: Perimeter of square = 4 × Side. Using this, ➛ Perimeter of square = 4 × 11 cm ➛ Perimeter of square = 44 cm The perimeter of rectangle is also 44 cm as per above discussion. And we know that, Perimeter of rectangle = 2(Length + Breadth) Then, ➛ 2(16 cm + Breadth) = 44 cm ➛ 16 cm + Breadth = 22 cm ➛ Breadth = 6 cm And, We have to find the area of the rectangle also. Area of rectangle = Length × Breadth Using this, ➛ Area = 16 cm × 6 cm ➛ Area = 96 cm² Hence:- Breadth of the rectangle = 6 cm Area of the rectangle = 96 cm² And we are done! :D

A wire is bent to form a square of side 11cm if this wire is re should to form a rectangle of length 16 cm find the breadth of rectangle and area of rectangle

Answer»

Required ANSWER:-

A simple logic we have to apply here. We know that the same wire was used to make both the SHAPES. It means the length of the wire is same for both square and rectangle. Hence the perimeter of square = perimeter of rectangle $.$

Now,

We already have the side of the square, So we can find the perimeter of square because:

Perimeter of square = 4 × Side.

Using this,

➛ Perimeter of square = 4 × 11 cm

➛ Perimeter of square = 44 cm

The perimeter of rectangle is also 44 cm as per above discussion. And we know that,

Perimeter of rectangle = 2(Length + Breadth)

Then,

➛ 2(16 cm + Breadth) = 44 cm

➛ 16 cm + Breadth = 22 cm

➛ Breadth = 6 cm

And,

We have to find the area of the rectangle also.

Area of rectangle = Length × Breadth

Using this,

➛ Area = 16 cm × 6 cm

➛ Area = 96 cm²

Hence:-

Breadth of the rectangle = 6 cm
Area of the rectangle = 96 cm²

And we are done! :D

Answer»

${\blue{\underline{\underline{\purple{\textsf{\textbf{Answer : }}}}}}}$

$\longrightarrow \sf \frac{10}{3} \\$

${\blue{\underline{\underline{\purple{\textsf{\textbf{Explanation : }}}}}}}$

Given that, the product of two NUMBERS is $\rm \dfrac{3}{2} \\$ . And one of them is $\rm - \dfrac{9}{20}$

➡ If we ASSUME the other number as x

Equation can be formed :

$\\ \rm \longrightarrow \frac{ - 9}{20} \times x = \frac{3}{2} \\$

❐ According to the QUESTION :

$\sf ⇒ \: \frac{ - 9x}{20} = \frac{3}{2} \\$

$\sf ⇒ \: x = \frac{3 \times {20}}{ 2 \times (- 9) } \\$

$\sf ⇒ \: x = \frac{ - 60}{18} \\$

$\green{\sf ⇒ x = - \frac{10}{3} \: ans}$

${\blue{\underline{\underline{\purple{\textsf{\textbf{Hence, The other number is :}}}}}}}$

$\huge \longrightarrow \sf - \frac{10}{3} \\$

NOTE behind :

Here, a product is given of two numbers where a number is mentioned definitely and on the other hand we have assumed the number as x . So, forming an equation get the VALUE of x will be the other number.

3M - 1/5 - m/7 = 3

3m - m/7 = 3 + 1/5

( 21m - m ) / 7 = ( 15 + 1 ) / 5

20m / 7 = 16 / 5

20m x 5 = 16 x 7

100M = 112

m = 112/100

m = 1.12
