Question 1 Surface Area And Volume Of A Cuboid And Cube Exercise 18.2
A cuboidal water tank is 6 m long, 5 m wide and 4.5 m deep. How many liters of water can it hold?
Answer:
Dimensions of a cuboidal water tank: Length = l = 6m Breadth = b = 5m Height = h = 4.5m We know, Volume of the cuboidal water tank = lbh By substituting the values, we get Volume = 6×5×4.5 = 135 Therefore, Volume of the cuboidal water tank is 135 m3 Convert into liters: We know; 1 m3 = 1000 liters So, 135m3 = (135×1000)liters = 135000 liters Hence, the tank can hold 1,35,000 liters of water.

"hello students welcome to lido q a video
session i am seth your math tutor and
question for today is
a cuboidal water tank is 6 meter long 5
meter wide
and 4.5 meter deep how many liters of
water it can hold
so dimensions of the cuboidal tanks are
given that
are
length that is let us consider length to
be l
which is equal to 6 meter
breadth
that is b and that is equal to 5 meter
and height
that is h and that is equal to 4.5 meter
from the question
now we know that the volume of the
cuboidal tank can be given by
length into breadth into height so that
is the formula for volume of the
cuboidal tank
and hence by substituting each of these
values you will get
6 into 5 into 4.5
and that is equal to 135
meter cube now here we have the
meter cube we don't we need to convert
this meter cube into liters
so we know that
we know 1 meter cube will be equal to
1000 liters
therefore 135
meter cube will be equal to 135
into 1000
and this will give you
1 lakh 35 000
liters
hence the tank can hold up to 1 lakh 35
000 liters of water
and that is our answer if you have any
doubt regarding this
you can drop it down in your comment
section and subscribe to lido for more
such interesting
q a thank you for watching
