Question

a rectangular water resevoir contains 105m.cube of water find the depth of water in the reservoir if its base measures 12m*3.5

Answer 1

Answer:

0.25 m

Step-by-step explanation:

10.5 / (12*3.5)

= 3/12

= 1/4

= 0.25 m

Answer 2

________________________________________________________

→ Given Question:-

   ⇒ A rectangular water reservoir contains 105 m^3 of water. Find the depth of the water in the reservoir if its base measures 12 m by 3.5 m.

_______________________________________________________

→ Solution:-

    ⇒ Water reservoir contains = 105m³

     ⇒ Length = 12m

     ⇒ width   =  3.5m

     ⇒ Let the depth of the water in the reservoir be ...

    ⇒ $x$

     ⇒ So, l × b × h = 105

     ⇒ 12 × 3.5 × h  = 105

     ⇒ h = $\frac{105}{12 X 3.5}$

     ⇒ h = 2.5m

     ⇒ ∴ Depth of the reservoir is 2.5m.
