A 3-dimensional shape consists of 24 small cubes of equal sizes. If the shape has a volume of 600〖cm〗^3, calculate the length of a side of the small cubes. (5)

1 answer

To find the length of a side of the small cubes, we need to follow these steps:

  1. Determine the volume of one small cube: Since there are 24 small cubes in total and the total volume of the shape is 600 cm³, we can find the volume of one small cube by dividing the total volume by the number of cubes:

    \[ \text{Volume of one cube} = \frac{\text{Total Volume}}{\text{Number of cubes}} = \frac{600 , \text{cm}^3}{24} = 25 , \text{cm}^3 \]

  2. Calculate the length of a side of one cube: The volume \( V \) of a cube is given by the formula:

    \[ V = s^3 \]

    where \( s \) is the length of a side of the cube. We can take the cube root of the volume of one small cube to find \( s \):

    \[ s = \sqrt[3]{25 , \text{cm}^3} \]

  3. Convert the result to a numerical value:

    \[ s \approx 2.924 \text{ cm} \]

Thus, the length of a side of the small cubes is approximately \( 2.92 , \text{cm} \) (rounded to two decimal places).
