<h2>Answer:</h2>

Length of the side of each small cube = 10cm

Area of the top surface of each small cube​ = 100cm²

<h2>Step-by-step explanation:</h2>

Big cube volume = s³

Big cube volume = 30³

Big cube volume = 27000cm³

Small cube volume = 27000 / 27

Small cube volume = 1000cm³

Small cube length = ∛1000

Small cube length = 10cm

Area of the top surface of each small cube = s x s

Area of the top surface of each small cube = 10 x 10

Area of the top surface of each small cube = 100cm²

What is the range of h (x)
Svet_ta [14]

The range of the function is the set of all possible outputs, that is, the set of all values obtained by applying the function to elements of the domain. So the set of all values which can be obtained by applying h(x) to an element of its domain is {−4,0,5,60} , and thus that is the range of h(x) .
