Question

1. remove each potato stick from its solution, and carefully blot the water from its surface. measure the length of each side of each potato stick and record below. length of side 1 length of side 2 length of side 3 potato stick 1 potato stick 2 5.5 continue » potato stick 3 5.5 5.5cm student name: 1 calculate the volume of each potato stick before and after soaking in the solution. how does the volume of each stick before soaking compare to the volume after soaking?

Explanation:

Step1: Assume potato - stick is a rectangular prism

Volume formula for rectangular prism is $V = l\times w\times h$. Since only one - side length (5.5 cm) is given, assume it's a cube for simplicity ($l = w=h$).

Step2: Calculate volume before soaking

For a cube with side length $a = 5.5$ cm, the volume $V_1=a^3$. So $V_1=(5.5)^3=5.5\times5.5\times5.5 = 166.375$ $cm^3$.

Step3: Without data after soaking

Since no data about the side - lengths after soaking is provided, we can't calculate the exact volume after soaking. But if it absorbs water, its volume will increase; if it loses water (in a hypertonic solution), its volume will decrease.

Answer:

The volume of each potato stick before soaking (assuming it's a cube) is 166.375 $cm^3$. We can't calculate the volume after soaking without more data, but if it absorbs water, volume increases; if it loses water, volume decreases.
