Answer:
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
Answer:
The answer is 1122.
Step-by-step explanation:
First, multiply 34 by 3. That gives you 102.
Then multiply 34 by 3 again. But when you're writing this down in calculations, put a zero in the ones column then write your answer. (I'll show an example of what this looks like at the bottom.
Then, add your answers and you'll have your answer...
