    The volume is also tripled when one length of the prism is tripled. It becomes 180 cubic inches instead of 60 cubic inches.

    Step-by-step explanation:

    Volume is the measurement of the amount a 3D object can hold. Each 3D object has 3 measurements: length, width, and height ... This object is a rectangular prism. Its volume is found as V = l*w*h. Substitute h = 4, l = 5, and w = 3. Then simplify for the volume.

    V = l*w*h

    V = 5*3*4

    V = 60 cubic inches

    Now repeat the process except multiply the depth by 3. So the length 5 inches becomes 15 inches. Substitute and simplify.

    V = 15*3*4

    V = 180 cubic inches

    The volume is also tripled when one length of the prism is tripled.
