A brick has a mass of 100 G and a volume of 25CM3 what is the density of the brick
kumpel [21]

Answer:

\boxed {\boxed {\sf 4 \ g/cm^3}}

Explanation:

We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.

\rho= \frac{m}{v}

The mass of the brick is 100 grams and the volume is 25 cubic centimeters.

  • m= 100 g
  • v= 25 cm³

Substitute the values into the formula.

\rho= \frac{ 100 \ g}{25 \ cm^3}

Divide.

\rho=4 \ g/cm^3

The density of the brick is <u>4 grams per cubic centimeter.</u>

Plantae - is the multicellular kingdom of the eukaryotic cells and as they produce their own food by photosynthesis called autotrophs.

protists - the autotrophic protists that are multicellular comes under algae, especially red algae.

Eukaryotic multicellular (heterotroph) -

Animalia - The Animalia kingdom is the kingdom of the heterotrophic eukaryotic organism that mostly has multicellular bodies. They depend on plants or other animals for their food.

Fungi - are mostly heterotrophic eukaryotic as they get their nutrient from other organisms are mostly multicellular.

Protist - some protists are heterotrophic as well.
