Question

A small bridge sits atop four cube shaped pillars that's all have the same volume . The combined volume of the four pillars are 500ft3 how many inches long are the sides of the pillars

Answer 1

Each cube separately has a volume of 125 ft^3, and the formula for a cubes volume is L x W x H. That means the solution is the cube root of 125, or simply, each side is 5 inches long. This is because 5 x 5 x 5 is equal to 125
