The formula for the volume of a pyramid can be found:
V =
, where B = area of the base and h = height of the pyramid
Since the base is a triangle, we need to use the formula for the area of a triangle:
A =
= 
Next, multiply the area of the base by the height of the pyramid:
17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³

Answer:
6
Step-by-step explanation:
4 1/2 / 0.75 = 4.5 / 0.75 = 6
Invested at 3% = x
invested at 4% = 2x
invested at 5% = x+500
0.03x + 0.04(2x) + 0.05(x+500) = 2025
0.03x + 0.08x +0.05x +25 = 2025
0.16x = 2000
x= 12,500
4% = 2x = 12,500 * 2 = $25,000
