Question

"Question 5 The capacity of a cuboidal tank is 50000 litres of water. Find the breadth of the tank, if its length and depth are respectively 2.5 m and 10 m.

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 the breadth of the tank be b m.

Given:

Length (l)=2.5 m  & depth (h) of tank =10 m &

Capacity of cuboidal tank=Volume of cuboidal tank=50000 L

= 50000 L= (50000/1000) m³= 50m³

 

Volume of cuboidal tank= 50 m³

 

[ 1 L=1/1000 m³]

Volume of cuboidal tank= l×b×h

50= 2.5×b×10

b=50/25=2

b=2m

Hence, the breadth of the cuboidal tank is 2 m.

Answer 2

Answer:

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

the breadth of the tank be b m.

Given:

Length

(l)=2.5 m  & depth (h)

of tank =10 m &

Capacity

of cuboidal tank=Volume of cuboidal tank=50000 L

=

50000 L= (50000/1000) m³= 50m³

 

Volume

of cuboidal tank= 50 m³

 

[

1 L=1/1000 m³]

Volume

of cuboidal tank= l×b×h

50=

2.5×b×10

b=50/25=2

b=2m

Hence, the breadth of the cuboidal

tank is 2 m.
