Final answer:
Sizes for sugary treats and beverages can vary but are often similar to related items whose sizes are more standardized. For example, a typical shake might be similar in size to a Starbuck's Grande Coffee at 16 ounces, or a cola drink typically at 12 ounces.
Step-by-step explanation:
The sizes in ounces for various food and drink items such as a Large Sundae, Concrete/Shake, and RB Float are not explicitly provided in the reference material. However, generally speaking, these dessert and beverage categories can vary in size, with some common sizes for milkshakes being around 11 to 16 ounces, similar to the provided Starbuck's Grande Coffee which is 16 ounces. By comparison, other beverages such as a cola or energy drink can range from 8 to 16 ounces. When measuring food products or beverages, common tools used include measuring cups and spoons, and glasses that typically measure 4 and 8 ounces of liquid. If available, servings of sundae or shakes could be measured using these tools.
The concrete/shake, likely a thick blend of ice cream and mix-ins, will vary in size by the establishment but may be comparable to other frozen treats like ice cream. The reference information mentions that coffee and coffee ice cream servings are typically 8 ounces, and this might be similar to a small shake size. An RB Float, presumably a root beer float, could also vary but might use a standard serving size of cola, which is often 12 ounces, not including the addition of ice cream.
