Answer:
142 in^2
Step-by-step explanation:
Base: 7 × 3 = 21 (×2 = 42)
Small faces: 5 × 3 = 15 (×2 = 30)
Larger faces: 5 × 7 = 35 (×2 = 70)
Add: 21 + 30 + 70 = 142
5.15625
This can be figured out by 1 divided by 2 five times then multiplying by five:
1/2 = 0.5
0.5 / 2 = 0.25
0.25 / 2 = 0.0125
0.0625 / 2 = 0.625
0.0125 / 2 = 0.03125
multiply 0.03125 by 5 and you get 5.15625
then add 5 to get 5.15625
I went in order from top to bottom. don't know if this was what you meant...... (1,2), (2,-2), (3,-6), (4,-10).
A/4 = 8/16
cross multiply
(16)(A) = (8)(4)
16A = 32
A = 32/16
A = 2
