Question

a water tank is 160cm long and 45cm deep. find the width of the tank if it contains 576 litres of water , given that 1litre=1000cu.cm

Answer 1

Breadth and depth of tank are 90 cm and 40 cm i.e. 0.90 m and 0.40 m respectively.
Suppose the length of water tank is l.
Then volume of tank = 0.90×0.40×l
And given volume of tank = 576 litres = 0.57600 m3, so we have;
0.90*0.40*l=0.57600
now,l=
$0.57600 \div 0.90 \times 0.40 = 1.6m$
Hence the Width of Tank is 1.6m
