Answer each correctly
Use the diagrams from page 3 for the following calculations:
Calculate the surface area of the total number of pieces of rice cake. Use the net of one of the pieces to help your calculations. Remember to multiply your answer by the total number of pieces.
Calculate the volume of one piece and the total volume of all pieces combined.
Calculate the rate of how much of the rice cake’s total volume was dissolved each second.
Plot the number of pieces vs. the surface area and the number of pieces vs. the rate of volume dissolved per second on the graph below. Use different colors to graph each set of data.
