Tamura's has small ice cream sandwich that are 2 inches wide, 6 inches long and 1 inch tall and large ice cream sandwich that are 3 inches wide, 10 inches long and 2 inch tall. How much more paper will a class of 30 students need to throw away if you purchase the large ice cream sandwiches? Round your final answer to the nearest whole number.

Find the surface area of both

I calculate the difference to be 72 in^2

 

Multiply by 30: 72*30 = 2160
