It is known that the edge length of the first cube carton is 6cm, and the volume of the second cube carton is 127cm3 larger than that of the first carton. The edge length of the second carton is calculated

It is known that the edge length of the first cube carton is 6cm, and the volume of the second cube carton is 127cm3 larger than that of the first carton. The edge length of the second carton is calculated

Let the edge length of the second carton be ACM, ∵ it is known that the edge length of the first cube carton is 6cm, and the volume of the second cube carton is 127cm3 larger than that of the first carton, ∵ a3-63 = 127, ∵ A3 = 127 + 216 = 343, A3 = 343 = 73 ∵ a = 7cm
