Sound waves are both compressional and longitudinal, (although we frequently draw them as transverse waves).
Longitudinal waves are where the particles of matter collide into one another, pushing them into the next and then oscillating back. This is how sound travels. This is also why sound can only travel through a medium, it cannot travel through a vacuum, as is shown here:
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
