The height of a square pyramid-shaped gift box is one half the length of
Schach [20]

Answer:

15 inches

Step-by-step explanation:

Volume of a squre based pyramid :

V = a²(h/3)

a = base edge ; h = height

h =1/2 a

V = 4500

4500 = a² * (1/2a) ÷ 3

4500 = a² * a/2 * 1/3

4500 = a³/2 * 1/3

4500 = a³ / 6

27000 = a³

27000 = a³

Take the cube root of both sides

(27000)⅓ = a

30 = a

Recall:

h = 1/2a

h = 1/2(30)

h = 15 inches

FREE BRAINLIEST!! ill also answer questions that you have posted if you answer correctly!!!! (42pts)
Elza [17]

<em>Answer:</em>

∠WVR = 156

<em>Step-by-step explanation:</em>

Angles in a triangle add up to 180

∴ ∠SRT + RST + RTS = 180

∴ ∠SRT + 109 + 47 = 180

∠SRT = 24

Alternate Angle Theorem

∠SRT = 180 - ∠WVR

24 = 180 - ∠WVR

24 - 180 = - ∠WVR

-156 = - ∠WVR

∠WVR = 156

Have a beautiful day.
