Okay. A square pyramid has 5 faces. So a pyramid with twice that would have 10 faces. You subtract 1 for the base and you get nine. Therefore you have 9 sides. Divide 72 by 9 and you get 8. So one side is 8 ft.
The only pyramid with a square base that has equilateral faces, is one where the diagonal of the base is exactly twice as long as the pyramid is high.
triangular pyramid
The area of a square is equal to twice the square's perimeter.
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
A shape where the perimeter is twice the area is a square. If we denote the side length of the square as ( s ), the perimeter ( P ) is ( 4s ) and the area ( A ) is ( s^2 ). Setting the perimeter equal to twice the area gives the equation ( 4s = 2s^2 ), which simplifies to ( s^2 - 2s = 0 ). This means ( s(s - 2) = 0 ), indicating that the side length can be 0 or 2, so a square of side length 2 has a perimeter of 8 and an area of 4, satisfying the condition.
Some do: a square 2 units on a side, for example, has area 4 units, perimeter 8.
Well, if you're talking about a square, then the perimeter is twice the length plus twice the width; in this case it would be 30 feet...
98 square feet
Yes, a shape can be drawn where the perimeter is numerically twice the area. A classic example is a rectangle with dimensions 2 units by 1 unit. The perimeter of this rectangle is 2(2 + 1) = 6 units, while the area is 2 × 1 = 2 square units. Here, the perimeter (6) is indeed twice the area (2).
no Actually, yes. The four sides can be labeled A, B, C, D. Doubling each side gives 2A, 2B, 2C, and 2D. Factoring out the two gives the expression 2*(A+B+C+D). We recognize (A+B+C+D) as the perimeter of the square. 2*(the perimeter of the square) is twice the perimeter of the square.
This has several values.The perimeter is twice the sum of any two numbers whose product is 54.
The perimeter is also twice as large.
