Answer:
volume of pyramid = (1/3) base area * height
= 1/3* 220*220*150
= 220*220*50
= 2420000 cubic m
now, height of lateral triangle is hypotenuse for right triangle with sides 150 and 110
height of triangle = √150^2+110^2
=√22500+12100
= √34600
= 186 approx
lateral area = 4*(1/2)*220*186
= 81840 sqm
