Math Problem Statement

An ice cube measuring 5.80cm by 5.80cm by 5.80cm has a density of 0.917 g/mL. What is the mass?

Solution

To calculate the mass of the ice cube, we can use the following formula:

Mass=Density×Volume\text{Mass} = \text{Density} \times \text{Volume}

Step 1: Calculate the volume of the ice cube.

The ice cube has dimensions of 5.80cm×5.80cm×5.80cm5.80 \, \text{cm} \times 5.80 \, \text{cm} \times 5.80 \, \text{cm}. Since the ice cube is a cube, the volume (VV) is calculated as:

V=5.803=195.112cm3V = 5.80^3 = 195.112 \, \text{cm}^3

Step 2: Use the density to calculate the mass.

The density of the ice cube is given as 0.917g/mL0.917 \, \text{g/mL}. Since 1 mL is equal to 1 cm³, we can directly use this in our formula.

Mass=0.917g/cm3×195.112cm3=178.949g\text{Mass} = 0.917 \, \text{g/cm}^3 \times 195.112 \, \text{cm}^3 = 178.949 \, \text{g}

Final Answer:

The mass of the ice cube is approximately 178.95 grams.
