The surface area of square pyramid is 64 ft²
What is square pyramid?
In terms of geometry, a square pyramid is a pyramid with a square base and four lateral faces. A pyramid is a type of polyhedron with three or more triangular faces that meet above its base (the apex). A square pyramid is a pentahedron, a three-dimensional shape with a total of five faces. The Great Pyramid of Giza is a well-known example of a real-life pyramid. When we learn about pyramids, we must also learn other concepts that are related to them, such as the volume and area of the pyramid. In this article, we will learn what a square pyramid is, its types, characteristics, surface area formulas, and volume formulas with numerous examples and solutions.
For a square pyramid, the surface area is given by the following equation:
SA = a^2 + 4(a)(h)
where a is the side length of the base and h is the slant height.
In this case, a = 4 and h = 3. Therefore,
SA = 4^2 + 4(4)(3)
SA = 16 + 48
SA = 64 ft^2

Perimeter of circular area = πr = 3.14 * 10 = 31.4 mm
Perimeter of rectangular area = 30 + 20 + 30 = 80 mm
Total Perimeter = 80 + 31.4 = 111.4
In short, Your Answer would be 111.4 mm
Hope this helps!

Answer:
The 1st answer.
Step-by-step explanation:
1. Find the quotient to 1/3 ÷ 3/4
Your quotient should be 4/9
2. Solve all of the expressions
1st answer choice product: 4/9
2nd answer choice product: 4
3rd answer choice product: 2 1/4
4th answer choice product: 1/4
3. The only answer that was equivalent to 1/3 ÷ 3/4 was answer choice 1 therefore the first answer choice was the correct answer choice.
