Question

The dimensions of a rectangular water tank are 2 m 75 cm by 1 m 80 cm by 1 in 40 cm. How many litres of water does it hold when filled to the brim?

Answer 1

Length of water tank (l)=2 m 75 cm =2.75 m

breadth (b)=1 m 80 cm =1.80 m

and height (h)=1 m 40 cm =1.40 m

$\therefore$ Volume of water filled in it =l.b.h=$2.75\times 1.80\times 1.40m^3$

$=6.93m^3$

Water in litres $=6.93\times 1000$

=6930 litres $(1m^3$ =1000 litres)
