Question

If your favorite cake frosting has a density of 1.08 g/cm^3 and is sold in 5.0 lb containers, how many containers would you need to purchase to frost a 40. inch x 25. inch sheet cake for a party if you wanted a generous 1.00 cm thick frosting?

Answer 1

V= abc = 40 x 25 x 1 = 1000 cm^3.

1000 x 1.08 = 1080.
