There are two basic styles. 1. Rectangular Prisms 2. Cubes

Rectangular prisms: • In our context, one dimension is longer than the others. (In culinary, every knife cut we do is a type of rectangular prism. )

Rectangular Prisms (all units are in inches) • Batonnet: (ba-tun-AY) Cut slightly thicker than Julienne. • Julienne: (jew-lee-EN) Cut into long, thin, rectangular pieces. • French Fry:

Cubes: all the dimensions are the same. (These are a special kind of prism. )

Cubes (all measurements are in inches) • Dice: • Brunoise: Very small dice • Mince: Cut very fine and evenly (Tiny dice) • Coarse Chop: Large dice

Other cuts • Diagonal: Cut into pieces with diagonal ends.

Extension--Class Discussion 1. What is the approximate number of large dice that can be cut from a 2 pound loaf of cheese?

Extension--Class Discussion 1. First you have to know the dimensions of the loaf of cheese (6 inches by 2 inches by 3 inches). Remember, each side of the large dice is inch. Since the large dice do not fit exactly in the loaf, you have to work with each measurement separately.

8 cubes can be cut from the 6 inch side. or Since doesn’t go into 2 evenly, we have waste and can only get 2 cubes from this side. 4 cubes can be cut from the 3 inch side.

cubes 4 2 8

• Because of the waste factor, you can not just multiply the dimensions of the cheese together (volume of the cheese loaf) and divide by (the volume of the dice).

2. How much cheese will we need if we double one of the measurements?

2. How much cheese will we need if we double one of the measurements? Ans: Only one of the dimensions needs to be doubled to get twice the number of cubes.

Extension 3. You are designing a studio room for a talk show. You need 480 cubic feet of air person. If the dimensions of your room are 50 feet by 60 feet by 12 feet, how many people can the room hold?

Extension 3. Ans: 75 people Total cubic feet of air in room divided by the amount of air per needed person (480 cubic feet) is the number of people (75).
