Mathematics
1 answer:
Tamiku [17]3 years ago
4 0

Answer:

x = 21

Step-by-step explanation:

3x - 23 = 40

Collect like terms

3x = 40 + 23

3x = 63

Divide through by 3

3x/3 = 63/3

x = 21

Check

3x - 23 = 40

since x = 21

3(21) - 23 = 40

63 - 23 = 40

40 = 40

Volume of a quadrangular pyramid=(1/3)bh
b=base
h=height

b=area of the base=area of a square=8.4 ft * 8.4 ft=70.56 ft²

Pythagoras theorem:
hypotenuse²=leg₁² + leg₂²

data:
hypotenuse=9.6 ft
leg₁=height=h
leg₂=8.4 ft /2=4.2 ft

(9.6 ft)²= h² + (4.2 ft)²
92.16 ft²=h²+17.64 ft²
h²=92.16 ft²-17.64 ft²
h²=74.52 ft²
h=√(74.52 ft²)=8.63 ft.

Volume of this quadrangular pyramid=(1/3)(70.56 ft²)(8.63 ft)=202.9 ft³≈202.3 ft³

Answer: ≈202.3 ft³
