Describe the net of a square pyramid

A net can also serve as a pattern to build a three-dimensional solid. A pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex. Surface area is the total area of all of the surfaces of a three-dimensional object. - Google

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

20 percentage, you can also do it on a calculator.
