Answer:
F
Step-by-step explanation:
The formula for the volume of a square-based pyramid is:
V = a2(h/3), where "V" is equal to volume, "a" is equal to base edge, and "h" is equal to height.
You are given the value of the base edge (a = 6)
If the base edge is equal to (1/2)h, or (1/2)h = 6 then, 2(1/2)h = 2(6). This gives you h = 12.
Now you just plug into your formula:
V = 62(12/3) = 36(4) = 144
pls mark brainliest.
The correct options are options B and C.
Percentage increases/decreases can be found using multiplication, you can't find 8% higher than T using addition.
I tested this by substituting T with 5.
Option A: 5 + 8 = 13
Option B:
= 1.08 --- 1.08 × 5 = 5.40
Option C: 1.08 × 5 = 5.40
Option D: 5 + 0.08 = 5.08
Hope this helpsss :)
