volume of pyramid = 1/3 ×(base area)× height
perimeter of base= 16 m
side length = 16/4= 4 m
so,
              volume  = 1/3× (4×4) ×3
                            =16 m³

given :
height is 3m
perimeter of it base 16m

required to be proved :
the volume of the pyramid

the formula required to solve this problem = 1/3*(base area)*height
=> perimeter of base = 16m
side length = 16/4 = 4
∴ volume = 1/3*(4*4)*3 = 16m³
