Answer :
Answer:
a) Length = 0.215 meter, width= 0.065 meter, height= 0.1025 meter.
b) The volume of the brick = 0.0014324375 meter^3.
c) Density of the brick = 1954.71007 kg/m^3.
Explanation:
a) As we know 1 meter = 1000 millimeters.
In other words, we can say a millimeter is a unit of length equal to one thousand a meter.
So, to convert, we have to divide the given numbers by 1000.
and we get :
Length = 215/1000 = 0.215 meter,
width= 65/1000 = 0.065 meter,
height= 102.5/1000 = 0.1025 meter.
b) It is known that a brick has the shape of a rectangle. And formula to calculate the volume of a rectangle is as follows.
Volume of rectangle = length × height × width
Since, it is given that length is 0.215 meter , height is 0.1025 meter and width is 0.065 meter . Therefore, calculate the volume of brick as follows.
Volume of brick = length × height × width
= 0.215 m × 0.1025 m × 0.1025 m
= 0.0014324375 meter^3
Hence, we can conclude that volume of the brick is 0.0014324375 meter^3 .
c) using the formula
ρ = m/V
ρ stands for DENSITY!
2.8 kilogram/ 0.0014324375 cubic meter (/=divided by....)
gives you the answer of 1954.71007 kg/m^3.
