Answer:
length of base(l) = 14m
slant height (s)=25m
we know,
slant height(s)=√(l/2)^2 + h^2
or, 25= √(14/2)^2+ h^2
or, 25 = √49+h^2
or, 25^2 = 49+h^2
or, 625 = 49 + h^2
or, 625-49=h^2
or, √576 =h
h=24
Therefore vertical height (h)= 24m
Again,
Volume of square pyramid (v) = 1/3 L^2h
or, v =( 1/3) 14^2×24
or, v= 4704 / 3
Therefore, V= 1568 cubic meter.
