  1. Asked: In:

    A cube is a three-dimensional figure. It has six faces and all of them are identical squares. The length of an edge of the cube is given by l. find the formula for the total length of the edges of a cube.

    Aasin

    Length of one edge of cube = l Number of edges in a cube = 12 Therefore, total length = 12xl = 12l https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Length of one edge of cube = l
    Number of edges in a cube = 12
    Therefore, total length = 12xl = 12l

  2. Asked: In:

    The side of a regular hexagon is denoted by l. Express the perimeter of the hexagon using l. (Hint: A regular hexagon has all its six sides in length)

    Aasin

    Side of hexagon = l Therefore, Perimeter of Hexagon = 6 x side = 6l https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Side of hexagon = l
    Therefore, Perimeter of Hexagon = 6 x side = 6l

  3. Asked: In:

    The side of an equilateral triangle is shown by l Express the perimeter of the equilateral triangle using l.

    Aasin

    Side of equilateral triangle = l Therefore, Perimeter of equilateral triangle = 3 x side = 3l https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Side of equilateral triangle = l
    Therefore, Perimeter of equilateral triangle = 3 x side = 3l

  4. Asked: In:

    Oranges are to be transferred from larger boxes into smaller boxes. When a large box is emptied, the oranges from it fill two smaller boxes and still 10 oranges remain outside. If the number of oranges in a small box are taken to be x, what is the number of oranges in the larger box?

    Aasin

    Number of oranges in one box = x Number of boxes = 2 Therefore, total number of oranges in boxes = 2x Remaining oranges = 10 Thus, number of oranges = 2x+10 https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Number of oranges in one box = x
    Number of boxes = 2
    Therefore, total number of oranges in boxes = 2x
    Remaining oranges = 10
    Thus, number of oranges = 2x+10

  6. Asked: In:

    Mother has made laddus. She gives some laddus to guests and family members; still 5 laddus remain. If the number of laddus mother gave away, l is how many laddus did she make?

    Aasin

    Number of laddus gave away = l Number of laddus remaining = 5 Total number of laddus = (l+5) https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Number of laddus gave away = l
    Number of laddus remaining = 5
    Total number of laddus = (l+5)

  7. Asked: In:

    Leela is Radha’s younger sister. Leela is 4 years younger than Radha. Can you write Leela’s age in terms of Radha’s age? Take Radha’s age to be x years.

    Aasin

    Radha’s age = x years Therefore, Leela’s age = (x-4) years https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Radha’s age = x years
    Therefore, Leela’s age = (x-4) years

  8. Asked: In:

    Radha is drawing a dot Rangoli (a beautiful pattern of lines joining dots with chalk powder as in figure). She has 8 dots in a row. How many dots will her Rangoli have for r rows? How many dots are there if there are 8 rows? If there are 10 rows?

    Aasin

    Number of dots in each row = 8 dots Number of rows = r Therefore, number of dots = 8r When there are 8 rows, then number of dots = 8 x 8 = 64 dots When there are 10 rows, then number of dots = 8 x 10 = 80 dots https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Number of dots in each row = 8 dots
    Number of rows = r
    Therefore, number of dots = 8r
    When there are 8 rows, then number of dots = 8 x 8 = 64 dots
    When there are 10 rows, then number of dots = 8 x 10 = 80 dots

  9. Asked: In:

    A bird flies 1 kilometer in one minute. Can you express the distance covered by the bird in terms of its flying time in minutes? (Use t for flying time in minutes)

    Aasin

    Time taken by bird = t minutes Speed of bird = 1 km per minute Therefore, Distance covered by bird = speed x time = 1xt= t km https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Time taken by bird = t minutes
    Speed of bird = 1 km per minute
    Therefore, Distance covered by bird = speed x time = 1xt= t km

  11. Asked: In:

    The teacher distributes 5 pencils per student. Can you tell how many pencils are needed, given the number of students? (Use s for the number of students)

    Aasin

    Number of students = s Number of pencils to each student = 5 Therefore, total number of pencils needed are = 5s

    Number of students = s
    Number of pencils to each student = 5
    Therefore, total number of pencils needed are = 5s

  12. Asked: In:

    If there are 50 mangoes in a box, how will you write the total number of mangoes in terms of the number of boxes? (Use b for the number of boxes)

    Aasin

    Number of boxes = b Number of mangoes in each box = 50 Therefore, total number of mangoes = 50b https://www.tiwariacademy.com/ncert-solutions/class-6/maths/chapter-11/

    Number of boxes = b
    Number of mangoes in each box = 50
    Therefore, total number of mangoes = 50b
