Final answer:
The size of a cube with a volume of 40 cubic inches is approximately 3.42 inches per side, calculated by taking the cube root of the volume.
Step-by-step explanation:
To find the size of a cube with a volume of 40 cubic inches, we need to calculate the side length of the cube. Since the volume of a cube is given by the formula V = s^3, where V is the volume and s is the side length, we can rearrange the formula to solve for s. Taking the cube root of both sides, we get s = V^(1/3). Plugging in the given volume of 40 cubic inches, we find that the side length of the cube is approximately 3.42 inches.
The question is about finding the size of a cube with a given volume. In mathematics, volume is the amount of space occupied by a three-dimensional object, such as a cube. The volume of a cube can be found using the formula V = s³, where V represents the volume and s represents the length of a side of the cube.
To find the side length of a cube when the volume is known, such as a cube with a volume of 40 cubic inches, the cube root of the volume must be taken. The cube root of 40 is approximately 3.42 inches, so each side of the cube is 3.42 inches long.
