Answer:

width: 1.9 ft
length: 2.3 ft
height: 1.7 ft

Step-by-step explanation:

The volume of a rectilinear shape is given by ...

V = W·L·H . . . . . where W, L, and H represent width, length, and height

Filling in the given information, we want to find a solution to ...

7.4 = x(x +0.4)(x -0.2)

If we write ...

f(x) = x(x +0.4)(x -0.2)

Then we're looking for the value of x that satisfies ...

f(x) -7.4 = 0

The attached graph shows that value to be 1.897, about 1.9 (feet). Then the desired kennel dimensions are ...

width: 1.9 ft
length: 2.3 ft
height: 1.7 ft
