Answer 2

243 cm³

Explanation:

A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that

Length x width = 9 square centimeters

But, since length and width are the same, we have that they are equal to
`√(9) =3` cms (since 3² = 9).

Thus, the volume of each cube is 3³ = 27 cm³

We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.

Volume of prism = 9 (27) = 243 cm³
