Answer:
Step-by-step explanation:
Height (h₁) of one square pyramid = 12 m
A similar pyramid has a height h₂ = 6 m
(a) Therefore scale factor of smaller pyramid to the larger pyramid =
=
= 1 : 2
(f) Since ratio of the sides of smaller to larger pyramid is 1 : 2
so ratio of area of the bases =
= 
= 
(g) Ratio of volume of smaller to larger pyramid
=
= 
(h) Since
=
and V₁ = 400 m³
So
=
⇒
= 
V₂ =
= 50 m³
