Math Problem Statement

A and B are two similar vases, not drawn to scale. The difference between the volume of vase A and the volume of vase B is 1197 cm³. Calculate the volume of vase A.

Solution

Given that vases AA and BB are similar, we know that their volumes are proportional to the cube of their corresponding linear dimensions. The height of vase AA is 10cm10 \, \text{cm} and the height of vase BB is 15cm15 \, \text{cm}.

Step 1: Find the scale factor

The scale factor kk from vase AA to vase BB is: k=Height of BHeight of A=1510=1.5k = \frac{\text{Height of B}}{\text{Height of A}} = \frac{15}{10} = 1.5

Step 2: Apply the scale factor to find the volume ratio

Since the vases are similar, the ratio of their volumes is the cube of the linear scale factor: (Volume of BVolume of A)=k3=(1.5)3=3.375\left(\frac{\text{Volume of B}}{\text{Volume of A}}\right) = k^3 = (1.5)^3 = 3.375

Let VAV_A represent the volume of vase AA and VBV_B represent the volume of vase BB. Then: VB=3.375×VAV_B = 3.375 \times V_A

Step 3: Set up and solve the equation

We are given that the difference in volumes is 1197cm31197 \, \text{cm}^3, so: VBVA=1197V_B - V_A = 1197

Substitute VB=3.375×VAV_B = 3.375 \times V_A: 3.375VAVA=11973.375 \, V_A - V_A = 1197 (3.3751)VA=1197(3.375 - 1) \, V_A = 1197 2.375VA=11972.375 \, V_A = 1197 VA=11972.375=504cm3V_A = \frac{1197}{2.375} = 504 \, \text{cm}^3

Answer

The volume of vase AA is: 504cm3\boxed{504 \, \text{cm}^3}
