Final answer:
To find the density of the cube with a mass of 150g and side length of 5cm, calculate the volume (125 cm³) and divide the mass by this volume, resulting in a density of 1.2 g/cm³.
Step-by-step explanation:
To calculate the density of a cube, we use the formula:
Density = Mass / Volume
Given that the mass of the cube is 150g and each side is 5cm long, we first need to calculate the volume of the cube. The volume (V) of a cube is found by cubing the length of one side (L3).
Volume = L x L x L = 5cm x 5cm x 5cm = 125cm3
Now we can calculate density:
Density = 150g / 125cm3 = 1.2 g/cm3
So, the density of the cube is 1.2 grams per cubic centimeter.
