Final answer:
The length of an edge of a cooler that has a volume of 9261 in.³ is 21 inches, which is found by taking the cube root of the volume.
Step-by-step explanation:
The question involves calculating the length of an edge of a cube when given the volume. Since the volume of a cube is found by cubing the length of one of its edges (V = s³), we can find the edge length by taking the cube root of the volume. In this case, the volume of the cooler is given as 9261 in³. Therefore, the length of an edge is the cube root of 9261, which can be calculated as follows:
Edge length (s) = ∛9261 in³ = 21 in (rounded to nearest whole number)
