Answer 2

Answer:

1. The capacity of the tank is 5000 litres, when the volume of the tank is 5m3. Thus one meter cube volume is equal to 1000 litres.

2. Volume of the Water Tank= lbh= 3 x 2 x 1 = 6 m^3= 6 x 1000 = 6000 Litres.

3. cubical cistern means every side are equal.

L=S cm

B=S cm

H=S cm

Volume of Cistern=S×S×S=729000cm^3

⇒S ^3

=729000

⇒S=90 cm

side of base =S

Area of base (Square) =S×S=90×90=8100sq.cm
