Calculate Sand Height in a 64 cm³ Cube: Volume to Height Conversion

Question

Below is a cube with a volume equal to 64 cm3.

If we pour 32 cc of sand into the cube, how high will the sand reach?

Video Solution

Solution Steps

00:00 What height will the sand reach?
00:03 We'll use the formula for volume calculation (edge cubed)
00:07 We'll take the cube root
00:13 This is the edge length of the cube
00:16 The height is the edge of the cube
00:20 We'll calculate the volume ratio between the sand and the cube
00:25 This is the volume ratio
00:30 We'll multiply this ratio by height to find the sand height
00:33 We'll substitute the height value we found and solve to find the sand height
00:38 And this is the solution to the question

Step-by-Step Solution

To solve this problem, follow these steps:

  • Step 1: Calculate the side length of the cube.
    - The volume of the cube is 64cm364 \, \text{cm}^3. Using the formula for the volume of a cube, s3=64s^3 = 64.
    - Find ss: s=643=4cms = \sqrt[3]{64} = 4 \, \text{cm}.
  • Step 2: Determine the base area of the cube.
    - The base of the cube is a square with side length 4cm4 \, \text{cm}.
    - The area, AbaseA_{\text{base}}, is 4cm×4cm=16cm24 \, \text{cm} \times 4 \, \text{cm} = 16 \, \text{cm}^2.
  • Step 3: Calculate the height the sand will reach.
    - We have 32cm332 \, \text{cm}^3 of sand. Use the volume formula for height: 32=16×h32 = 16 \times h.
    - Solve for hh: h=3216=2cmh = \frac{32}{16} = 2 \, \text{cm}.

Therefore, the sand will reach a height of 2cm 2 \, \text{cm} in the cube.

Answer

2 2 cm
