Answer:
243 cm^3
Step-by-step explanation:
The faces of a cube are squares.
A = s^2
s^2 = 9 cm^2
s = 3 cm
The side of the square is the edge of the cube and is 3 cm.
V = s^3
V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3
The volume of one cube is 27 cm^3.
The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3
Answer: 243 cm^3
