For each pair of quantities given below, check whether the first is proportional to the second. For proportional quantities, calculate the constant of proportionality.

The volume of water poured into a hollow prism and the height of the water level.

The volume of water poured into a hollow prism and the height of the water level.


Let the volume of hollow prism be v and height of water level be h.


Let the base area of the prism be ‘a’


The poured volume = volume of the water column formed in the prism


But volume for water column in the prism = base × height


⇒ v = a × h


⇒ v = ah


⇒


We can whatever value we like for v on right side of the above equation. So, v is a variable. But a is a constant for a prism.


Whatever value we give for n, that the value will be multiplied by a constant . So, d will always be proportional to n.
