40 and 202.5 m³

Step-by-step explanation:

(7)

Since the figures are similar then the ratios of corresponding sides are equal, that is

= ( cross- multiply )

12 PQ = 480 ( divide both sides by 12 )

PQ = 40 in

The volume (V) of a pyramid is calculated as

V = Ah ( A is the area of the base and h the height ) , then

V = × 9² × 7.5

   = × 81 × 7.5

   = 27 × 7.5

   = 202.5 m³

my answer is$ 12

step-by-step explanation:
