Math Problem Statement

2 PASTA JARS ARE MATHEMETICALLY SIMILR, VOLUM EOF LARGER JAR IS 1.6L AND 30CM FIND THE VOLUM EOF SMALL JAR THATS 24CM

Solution

To solve this, we use the concept of similarity for the two jars. If the jars are mathematically similar, their corresponding dimensions are proportional, and the volumes relate to the cube of the ratio of their corresponding heights.

Given:

  • Volume of the larger jar (V1V_1) = 1.6 L
  • Height of the larger jar (h1h_1) = 30 cm
  • Height of the smaller jar (h2h_2) = 24 cm
  • Volume of the smaller jar (V2V_2) = ?

Step 1: Ratio of heights

Height ratio=h2h1=2430=45\text{Height ratio} = \frac{h_2}{h_1} = \frac{24}{30} = \frac{4}{5}

Step 2: Ratio of volumes

Since the volumes are proportional to the cube of the height ratio: V2V1=(h2h1)3=(45)3=64125\frac{V_2}{V_1} = \left(\frac{h_2}{h_1}\right)^3 = \left(\frac{4}{5}\right)^3 = \frac{64}{125}

Step 3: Solve for V2V_2

V2=V1×64125V_2 = V_1 \times \frac{64}{125} Substitute V1=1.6LV_1 = 1.6 \, \text{L}: V2=1.6×64125=102.4125=0.8192LV_2 = 1.6 \times \frac{64}{125} = \frac{102.4}{125} = 0.8192 \, \text{L}

Final Answer:

The volume of the smaller jar is approximately 0.82 L.
