We began chapter 7 today, learning about volume. The assignment today was p. 250-251 #3-14. Remember volume of regular prisms is the area of the base shape multiplied by the height. For cubes and rectangular prisms you can use length x width x height. For triangular prisms it is the base of the triangle multiplied by the height of the triangle (which are the two dimensions that form the right angle) multiplied by the height of the prism.
