First calculate the volume of the rectangular prism by multiplying its length, width and height. The volume of the prism is 8 cm^3. Since density is known to be mass over volume, just multiply the given density with the volume. The mass of the prism then is 960 grams.
and Since density is the ratio of the substance's mass to its volume,Density = Mass/Volume
Mass = Density*Volume
The volume of a rectangular prism is:
V = LWH = 4×2×1 = 8 cm³
Mass = (120 g/cm³)(8 cm³)
Mass = 960 grams
Answer:
mass = 960 g
Explanation:
The rectangular prism have a density, length , width and height. We are asked to calculate the mass of the rectangular prism from the data given above.
The density of an object measures the mass of the object to it volume. Mathematically, density is the mass of an object divided by it volume. It is represented as follows;
density = mass/volume
The density of the prism is known from the data given but the volume is not given . Base on the data given, one could compute volume of the rectangular prism.
volume of a rectangular prism = Length × width × height
length = 4cm
width = 2cm
height = 1cm
volume of a rectangular prism = 4 × 2 × 1
volume of a rectangular prism = 8cm³
Since the volume is known the mass can be computed from the density formula.
density = mass/volume
mass = density × volume
density = 120 g/cm³
volume = 8cm³
mass = 120 × 8
mass = 960 g
