Given:
base edge - 8 ft
altitude or height - 75 ft
Surface area = [(3√3)/2] a² + 3a[√h² + (3a²/4)]
S.A = 2.6*8² + 3(8) * √75² + [(3*8²)/4]
S.A = 166.4 + 24 * √5625 + 48
S.A = 166.4 + 24 * √5674
S.A = 166.4 + 24 * 75.33
S.A = 166.4 + 1807.92
S.A = 1974.32 ft²
convert square feet to square yard.
1 sq ft = 0.1111 sq yd
1974.32 ft² * 0.1111 sq.yd/sq.ft = 219.35 sq yd.
22 per sq. yard
219.35 sq. yard * $22/sq.yd = $4,825.70
Total cost is $4,825.70
Answer:
Primary succession is the orderly and predictable series of events through which a stable ecosystem forms in a previously uninhabited region. Primary succession occurs in regions characterized by the absence of soil and living organisms.
That would be integumentary system
The 8 characterstics of life are as follows:
1. Made of cells
2. Adapt and Respond to environment
3. Homeostasis or Internal Balance
4. Based on genetic code- DNA or RNA
5. Evolution- all organisms evolve over time
6. Consume energy
7. All organisms reproduce
8. All organisms grow and develop
