Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft

F = k / (r^2)
dF/dt = -2k / (r^3) dr/dt
When r = 10^4 km and dr/dt = 0.2 km/sec
dF/dt = -2(10)^3 (0.2) / ((10^4)^3) = -400 / 10^7 = -0.00004 N/s
The gravitational force is changing at the rate of -0.00004 N/s
