Question

"Question 3 A cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380 cubic metres of a liquid?

Class 9 - Math - Surface Areas and Volumes Page 228"

Answer 1

The space occupied by an object solid body is called the volume of the particular object solid body volume is always measured in cubic unit.

Volume of a liquid that can fill the interior of the hollow is called the capacity of the hollow object.

==========================================================

Solution:

Let h be the height of vessel

Given:

length(l)=10m

Breadth(b)=8m

Volume of cuboidal vessel= Liquid to be hold

 

Volume = 380 m³ (given)

Volume of cuboidal vessel= l x b x h

10 x 8 x h=380

h=380/80= 38/8

h=19 /4 =4.75m

Hence, the cuboidal vessel must be made 4.75m high.
