The designer should change the height of the can and maintain the same volume by doubling the area of the base of the can.
Area of a cylinder, V= πr²h
Where:
Area of the base, A= πr²
So,
volume of the cylinder;
V= A×h
For instance,
V= A*h
50 = 10 × h
50 = 10h
h = 50/10
h = 5cm
V= A×h
50 = 20 × h
50 = 20h
h = 50/20
h = 2.5 cm
