Question

A rectangular water reservoir contains 42000 litres of water. If the length of reservoir is 6 m and its breadth is 3.5 m. the depth of the reservoir is

(a) 2 m

(b) 5 m

(c) 6 m

(d) 8 m

Answer 1

Water in rectangular reservoir =42000 l

$\therefore$ Volume $=\frac{42000}{1000}=42m^3$

Length (l)=6 m

Breadth (b)=3.5 m

$\therefore$ Depth $=\frac{Volume}{l\times b}=\frac{42}{6\times 3.5}$

=2 m
