Question

A cold drink seller has two types of container.
i) cuboidal container of lenght 5cm ,width 4cm and height 10cm.
ii) a cylindrical container of diameter 7cm and height 10cm.
a) Which container has greater capacity? By how much?
b)If he sells them in same price,then which container gives more profit?
b)If seller motivates customer to purchase the cylindrical container, then which value is depicted from this act?

Answer 1

Volume of cuboidal container =5×4×10=200
Volume of cylindrical container=22/7×7/2×7/2×10=385
Cylindrical container has greater capacity than cuboidal container by 185 cm cube
Cylindrical container will give more profit
The value depicted by seller is ,he is calculative

Answer 2

a) The cylindrical container has more capacity by 185 cm³.

b) The cuboidal container gives him more profit.

c) The quality shown by the seller is that he is calculative and wants to earn more profit .

The volume of the cuboidal container = 5 × 4 × 10

= 200 cm³

The volume of the cylindrical container = π × (7/2)² × 10

= (22/7) × (49/4) × 10

= 385 cm³

The volume of the cylindrical container is greater than the cuboidal container by 185 cm³.

If he sells both the containers at the same price then the cuboidal container will give him more profit because for less volume he gets more money.
