Question

Bubble wrap sells in sheets, and each sheet has 1 million individual spherical bubbles, each with a diameter of 0.01 m. What is the total volume of air contained in the bubbles of two sheets of bubble wrap? Round to the nearest tenth.

Answer 1

Volume of each sphere = 4/3πr^3 = 4/3π(0.01/2)^3 = 5.236 x 10^-7
Volume of the 1 million bubles in 1 sheet = 1,000,000(5.236 x 10^-7) = 0.5236
Volume of air contained in the bubbles of 2 sheets of bubble wrap = 2(0.5236) = 1.047 cubic meters.
