When you divide 6x10^24 by 8x10^8 you end up with
This simplifies to
Now this number is not written in scientific notation as it does not have its first digit before the decimal, so we must move the decimal of this one to the right.
To do that you must multiply the number by 10.
This means that the exponet of 10 must decrease by 1.
This makes the answer
Answer:
a. What is the name of the 3D shape?
The name of the 3D shape is Prism
b. What is the formula for total surface area for this shape?
Total surface area:
c. What is the surface area of the figure?
The surface area of the figure is 144 cm²
Step-by-step explanation:
a. What is the name of the 3D shape?
The 3D shape has two congruent and parallel faces (triangles) and the other faces are parallelograms, then the 3D shape is a prism
b. What is the formula for total surface area for this shape?
Total Surface area:
where:
Area of the base of the prism: Ab
Perimeter of the base: Pb
Height of the prism: h
c. What is the surface area of the figure?
The base of the prism is a triangle. Then to calculate the area of the base, we must use the formula to calculate the area of a triangle:
The perimeter of the base is the perimeter of the triangle, equal to the sum of the sides of the triangle:
h: Height of the prism is the distance between the bases of the prism (the triangle), then h=11 cm
Then, replacing in the formula the known values:
