Surface Area to volume ratio 

Today we study the relationship between surface area and volume in organisms.  

We started with a cut-and-paste activity creating cubes with sides of 2.5 cm by 2.5 cm.  

surface area

    • In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

      1. synonyms: outsideexterior.

        the area of an outer part or uppermost layer of something. 

        noun: surface area “the surface area of a cube”
