6 cm
5 cm
7 cm
To find the length of the rectangular prism, we can use the formula for the volume of a rectangular prism: volume = length × width × height.
Given that the volume is 120 cm^3, the height is 4 cm, and the width is 5 cm, we can substitute these values into the formula:
120 cm^3 = length × 5 cm × 4 cm
Simplifying the equation, we have:
120 cm^3 = 20 cm × length
To solve for the length, we divide both sides of the equation by 20 cm:
length = 120 cm^3 / 20 cm
length = 6 cm
Therefore, the length of the rectangular prism is 6 cm.
