Question

"Question 2 A cuboidal water tank is 6 m long, 5 m wide and 4.5 m deep. How many litres of water can it hold? (1 m^3 = 1000l)

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

Answer 1

VOLUME:

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.

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

Given:

l = 6 m, b = 5 m & h = 4.5 m

 

Volume of cuboid= l×b×h

Volume of cuboidal water tank = (l × b × h)

=(6×5×4.5)m³

=135 m³

  [1m³=1000 L]

= 135000 L.

Hence, tank can hold 135000 L of water.

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

Hope this will you....

Answer 2

Dimensions = 6 ✖ 5 ✖ 4.5

we know that volume of cuboid=l*b*h

Volume = 6 ✖ 5 ✖ 4.5 m³ = 135m³

converting to the litres.

1m³=1000litres

135m³=135000litres

so number of litres the cuboidal water tank can hold = 135000 litres .

hope helped !....
