Julia bought a new sandbox and needs to know how much sand to buy. Her sandbox is a prism with a square base with sides of 8 inches, and a height of 12 inches. If she plans on filling her sandbox to the top, how many cubic inches of sand does she need?

Help yourself by helping us understand what you've done first. What have you tried? What do you know about prisms? Do need the surface area or volume? How would you start calculating that?

sides of 8 inches, and a height of 12 inches.

That's one small and strangely shaped sandbox.
