Solve :-
1). If a blue whale weighs 5000 kg and your weight is 25 kg. Guess how
many children of your weight will be equal to the weight of a blue whale? (2)
2). A playground has length 230 m and breadth 415 m. What is the perimeter
and area of the playground?
(4)
3) Find the volume of a cubic box A whose sides are 8 cm long. Find the
volume of a cubiod B whose length is 7 cm, width is 5 cm and height is 2 cm?.
Whose volume is bigger and by how much?​

Answer 1

Answer:

I apologize i don't know the answer and I am terrible at math.

Answer 2

Answer:

1. 5000/25 = 200

ANS = 200 children of 25g will be equal to the weight of the 5000 kg blue whale.

2. Lenght = 230 m ; Breadth = 415 m

Perimeter of the playground = 2 (l + b)

                                                => 2 (230 + 415)

                                                => 2 x 645 = 1290 m

ANS = The perimeter of the playground is 1290 m.

3. Volume of the cubic box = a^3

                                              => 8 x 8 x 8 = 512^3 cm

Volume of the cuboidal box = lbh

                                               => 7 x 5 x 2 = 70^3 cm

ANS = The volume of the cubic box is bigger by 442^3 cm.
