Frequently asked questions
What is the volume formula for a cube?
V = side³. A cube has three equal edges, so length × width × height collapses to one number cubed. Enter a side of 3 above and you get 27 cubic units, matching the worked example. A side of 10 cubes to exactly 1,000, meaning one thousand unit tiles fit inside.
How many faces and edges does a cube have?
6 square faces, 12 edges, and 8 corners — yet the volume needs only one measurement because every edge is identical. That is what makes the cube the simplest 3D solid to measure.
Are volume and surface area comparable?
No — they use different units, so comparing the raw numbers is meaningless even when the values cross over. A side-3 cube has volume 27 cubic units against surface area 54 square units; the units, not the numbers, tell the story.
