Lizette wanted to see if it would be possible to use a little less materials in a tea infuser but still not be required to be at full capacity. Her rectangular pyramidal tea infuser would be 7 cm high, 3 cm long and 1.5 cm wide. The tea infuser from the example, was the same except 7.9 cm high and was filled to 80% capacity.

Would these dimensions work, if so to what percent would Lizette's infusers have to be filled to use the same amount of tea?

Respuesta :

The percentage that the infuser will have to be filled to use the same amount of tea will be 90.23%.

How to calculate the percentage?

The infuser for Lizeete is 7 cm high, 3 cm long and 1.5 cm wide. The volume will be:

= 7 × 3 × 1.5

= 31.5cm³

The tea infuser from the example, was the same except 7.9 cm high. Therefore, the volume will be:

= 7.9 × 3 × 1.5

= 35.5

Since it was filed to 80%, this will be:

= 80% × 35.5

= 31.5cm³

Therefore, the dimensions will work and the percentage to use the same amount of tea will be:

= 28.44/31.5 × 100

= 90.23%
