The given pyramid's total surface area is 3. 24.0 square feet.
Step-by-step explanation:
Step 1:
To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.
There are 3 triangles and 1 square in the figure.
Step 2:
All the triangles are similar.
The surface area of a triangle =
The similar triangles have a base length of 3 feet and a height of 2.5 feet.
The surface area of 1 similar triangle = square feet.
The surface area for all the similar triangles = square feet.
Step 3:
The surface area of a square is the square of its side length. The square has a side length of 3 feet.
The surface area of the square = square feet.
Step 4:
To calculate the total surface area we sum up all the individual surface area.
The total surface area = square feet which is the third option.
That would be 548,900 / 1.6 = $343,062.50
Answer:
20/21
Step-by-step explanation:
Hello,
so we first of all cannot actually divide the fractions but we can use a strategy I have learned called stay, change, flip.
Basically you keep the first fraction the same, change the division sign to a multiplication sign and flip the second fraction.
so for this problem, we would keep the 4/7 the same, change the division sign to a multiplication sign, and flip the 3/5 over to make 5/3. We then would multiply this out, and get 20/21.
Hope this helped! ☻
