Here, we have,
Mass = 43 g
Volume = 12 cm^3
Density = ?
Using Formula,
Mass = Density * Volume
=> 43 g = Density * 12 cm^3
=> Density = 43/12 g/cm^3
=> Density = 3.58333 g/cm^3
The lateral area is the area of everything but the base. A shortcut formula for this area is Ph. (where P is the perimeter of the base and h is the height of the prism).
So the lateral area is (3+9+9.49)x37 = 795.13 m^2 or 795 m^2
The surface area is the lateral area plus the area of the 2 bases. The base is a triangle. (area = 1/2 bh)
Since there are two identical bases, the total area of the base is just 3x9 = 27
So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
1/3 = 4/12
(4/12 + 11/12) * 2/3
= 15/12 * 2/3
15/ 12 can also be written as 5/4
5/4 * 2/3 = 10/12
10/12 can be simplified into 5/6
Therefore, the answer is 5/6
Step-by-step explanation:
1 is the least and 3 is the greatest
