Find the mass of an iron bar that has the shape of a cuboid with dimensions equal to 6 cm, 10 cm, 15 cm, respectively, if the density of iron is 7.8 g / cm3.
Mass is density times volume.
1. First, find the volume of the iron bar. To do this, you need to multiply all its sides.
6 * 10 * 15 = 900 cubic centimeters
2. Now we find the mass of the bar by multiplying the density by the volume.
7.8 * 900 = 7020 grams
Answer: 7020 grams
