Answer:

466 cm^{3}

Step-by-step explanation:

Ok to solve this problem we need to find the volume of the rectangular prism and subtract the volume of the cube from it.

The volume of the rectangular prism is Length * Width * Height.

L = 15

W = 9

H = 4

15 * 9 * 4 = 530 cm^{3}

The volume of the cube is l^{3}

l = 4

4^3 = 64

530-64 = 466 cm^3
