I presume this question is actually asking "how many square feet are in five acres?" There are 43,560 square feet in one acre. Therefore, there are 217,800 square feet in five acres.
5 miles = 26,400 feet
5 millimeters = 0.0164042 foot (rounded)
177.8 cm.
5 faces,8 edges, and 5 vertices
No.
75 square feet
A square based pyramid has 5 vertices.
5: 4 triangular faces and 1 square bottom.
400.5
Assuming that a squre parimid is your way of spelling square pyramid, the answer is 5.
Multiplying 45 by 5 shouldn't be hard as that will give the answer is square feet
5.2461 feet. (about 5 feet 3 inches).
