What Percentage is Product?
What Percentage is Product?
We guessed maybe 40% is product.
Plan:
Plan:
- Measure the packaging, width, length and height in cm.
- Calculate the volume of the packaging.
- Calculate the percentage that is product, and the percentage which is packaging and air.
Measure:
Measure:
Length = 7cm
Length = 7cm
Width = 7cm
Width = 7cm
Heigth = 6.5 cm
Heigth = 6.5 cm
Calculate:
Calculate:
V=7*7*6.5
V=7*7*6.5
Volume = 318.5 cubic centimeters
Volume = 318.5 cubic centimeters
Capacity = 318.5 ml.
Capacity = 318.5 ml.
Percentage of Product = 50/318.5 = 0.1569858 = which rounds to 15.7 percent or roughly 16%
Percentage of Product = 50/318.5 = 0.1569858 = which rounds to 15.7 percent or roughly 16%
Percentage of air and packaging = (318.5-50)/318.5 = 0.8430 = which is approximately 84%
Percentage of air and packaging = (318.5-50)/318.5 = 0.8430 = which is approximately 84%
Conclude:
Conclude:
The packaging and air makes up approximately 84% of the volume of the product.
The packaging and air makes up approximately 84% of the volume of the product.
The product takes up approximately 16% of the volume of the external packaging.
The product takes up approximately 16% of the volume of the external packaging.
I think this is bad because:
- The box is not needed, and is wasteful for the environment.
- The plastic container could be smaller.
Next steps:
- Measure the external dimensions of the plastic container. (Level 5 of the NZC).
- Calculate the wasted space in the plastic container.
- Unfold the box and measure the surface area cardboard used to make it.
- Write to Nivea to explain the unnecessary packaging which wastes trees and creates rubbish.
The above example is Level 3 & 4 - Calculate the volume of a cuboid.

- Prime Climb Measurement
- Can we create a square prism, a triangular prism, a parallelogram prism, a trapezium prism and a cylinder with the exact same height and volume? Order the shapes by their expected surface area, and compare this with the actual surface areas.
