Answer:
6300 m³
Step-by-step explanation:
The volume of the pyramid is given by the formula ...
V = 1/3s²h
where s is the side length of the square base, and h is the height.
V = 1/3(30 m)²(21 m) = 6300 m³
The approximate volume of the pyramid is 6300 m³.
Answer:
a ≈ 21.8
Step-by-step explanation:
We require the third angle in the triangle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 31.8)° = 180° - 106.8° = 73.2°
Using the Sine rule, that is
= 
( cross- multiply )
a × sin75° = 22 × sin73.2° ( divide both sides by sin75° )
a = 
≈ 21.8 ( to the nearest tenth )
