Unit 4 – Item 10

The Rock Soda Company wants to design a new soda can that uses less aluminum. This would save money and be better for the environment. As a member of the Rock Soda Company design team, it is your responsibility to design a new can that reduces the amount of material needed for each can. The dimensions of the current can are shown below.

(Round your answers to the nearest hundredth. Use 3.14 for 𝜋).

null

Can Dimensions:

Diameter = 6.6 cm

Height = 12.27 cm

Your task includes:
Determine the volume and surface area of the current soda can.
Draw a net of the current can including dimensions.
Design a new can that has the same volume but uses less materials (lower surface area).
