Final answer:
The side length of a cube with a volume of 125 cubic inches is found by calculating the cube root of 125, which is 5 inches. Therefore, the correct answer is A) 5 inches.
Step-by-step explanation:
The question asks about the length of a side of a cube given its volume. To find the side length of the cube, we use the formula for the volume of a cube, which is V = s^3, where V is the volume and s is the side length. Given Matteo's cube has a volume of 125 cubic inches (125 in^3), we need to find the cube root of 125 to get the side length.
To calculate the cube root of 125, we look for a number that, when multiplied by itself three times (s * s * s), equals 125. Through calculation or memorization, we know that 5 * 5 * 5 = 125. Therefore, the cube root of 125 is 5, which means the side of the cube is 5 inches long. The correct answer is A) 5 in.
