Answer 2

Step-by-step explanation:

31)

The length of a cuboidal box (l) = 10 m

Let the breadth of the cuboidal box be b

The height of the cuboidal box (h) = 7m

We know that

The volume of a cuboid = lbh cubic units

=> 10×b×7

=> 70 b cubic metres

According to the given problem

The volume of the given box = 175 m³

=> 70 b = 175

=> b = 175/70

=> b = 35/14

=> b = 2.5 m

The breadth of the box. = 2.5 m

32)

a)

Given that

47 rupees and 70 paise

We know that

1 rupee = 100 paise

47 rupees = 47×100 paise

=> 47 rupees = 4700 paise

Now,

47 rupees and 70 paise

=> 4700+70

=> 4770 paise

b)

Given that

25.4 cm

We know that

1 cm = 10mm

=> 25.4 cm = 25.4×10 mm

=> 254 mm

33)

The weight of one chocolate = 80 g

Total weight of the box = 2kg

We know that

1 kg = 1000g

=> 2 kg = 2000g

The number of chocolates

= Total weight of the box / Weight of each chocolate

= 2000/80

= 200/8

= 25

The number of chocolates required = 25

34)

Let the length of the field be X m

Breadth of the field = 400 m

Area of a rectangle = lb sq.units

=> 400×X = 400X sq.m

According to the given problem

A rectangular field has an area of 1,80,000

=> 400X = 180000

=> X = 180000/400

=> X = 1800/4

=> X = 450

The length of the field = 450 m
