Volume of Mike's rectangular prism-shaped carton, V1 = L x W x H

Where L, W, H are the Length, Width and Height respectively

V1 = 5 x 3.5 x 7

= 122.5 cubic inch

Volume of Carol's cylindrical-shaped carton, V2 = πr2h

Where r is the radius and h is the height

r = diameter/2

r = 5/2 = 2.5

V2 = π(2.5)2(7)

= 137.4cubic inch

Thus, Carol's cylindrical-shaped carton will hold 137.4 - 122.5 more ice cream than Mike's rectangular prism-shaped carton

122.5 - 137.4 = 14.9
