Sandpyramiden — Hur räknar man ut volymen av en pyramid och en kon?

Volymen av en pyramid eller en kon är basytans area gånger höjden delat med 3 (V = B · h / 3), alltså en tredjedel av motsvarande prisma eller cylinder med samma bas och höjd. Du gissar hur högt sanden når när en sandpyramid hälls i en låda, fyller en cylinder med en kon och avgör om en sned pyramid rymmer lika mycket.
