1.	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. 8m
Answer» We know that, Volume of a cuboid = Length × Breadth × Height 42000 L = 42 m³ (As 1 m³ = 1000 L) Therefore, Height (h) = \(\frac{Volume}{Ib}\) = \(\frac{42}{6\times3.5}\) = 2 m Hence, option A is correct

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. 8m

Answer»

We know that,

Volume of a cuboid = Length × Breadth × Height

42000 L = 42 m³ (As 1 m³ = 1000 L)

Therefore,

Height (h) = \(\frac{Volume}{Ib}\)

= \(\frac{42}{6\times3.5}\)

= 2 m

Hence, option A is correct
