Answer:
Explanation:
You mean that every dimension is increased by 1/3, what is the change in volume?
Original tube
V = pi * r^2 * h
New Tube
V = pi * [(1 + 1/3)r]^2 * (1 + 1/3)*h
V = pi * (4/3)^2 r^2 * (4/3) * h
V = pi * (4/3)^3 r^*h
The new Tube has increased in volume by a factor of (4/3)^3 = 64/27 or approximately 2.03 times
