Question

a tank is 4 m long 2 m 50 cm wide and 3 M height find the capacity of the tank in l 1000 cm cube is equal to 1 litre​

Answer 1

Answer:

Surface area of a tank open at top = Surface area of cuboid - Area of the portion open at the top i.e. 2(50+15+30) - 50 = 2*95 - 50 = 190 -50 = 140m sq. The volume is equal to cross sectional area times the height. A litre is 1000 cm^2, so the volume will be 70 L/cm * D, the depth in cm.

Answer 2

Given:

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

⇒Volume of tank =l×b×h

⇒V=6×5×4.5=135m

3

⇒Amount of water hold by 1m

3

volume =1000l

Amount of water hold by 135m

3

volume

=135×1000

=135000l
