Answer:
5 m
Step-by-step explanation:
The volume (V) of a square based pyramid is
V = Ah ( A is the area of base and h the height ), thus
A × 12 = 100, that is
4A = 100 ( divide both sides by 4 )
A = 25
Hence s² = 25 ← s is the side of square base
Take the square root of both sides
s = = 5
Answer:
C
Step-by-step explanation:
This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.
