Question

The volume of a box(V) varies directly with its length(l). If a box in the group has a length of 30 inches and k = 24, what is its volume?

Answer 1

Alright, lets get started.

The length of the box = 30 inches

constant k = 24

Volume
`(V) = l*w*h`

Let
`w*h` are constant, then

`k = w*h`

volume of a box(V) varies directly with its length(l).

Means

`V= k l`

Putting the value of k and l in above equation

Volume V = 24 * 30

V = 720 inches cube : Answer
