Rectangular prism with a length of 9 inches he went to 2 inches and the height of 1 1/2 inches what is the surface of the box

69 in^2

Step-by-step explanation:

I will assume you meant the following:

length:  9 in

width:  2 in

height:  1.5 in

The area of (each) the top and bottom is L * W = (9 in)(2 in) = 18 in^2; twice that includes the total area of top and bottom and is 36 in^2.

The total area of the ends is 2(2 in)(1.5 in) = 6 in^2

The total area of the front and back is 2(9 in)(1 1/2 in) = 27 in^2

Thus, the total surface area is (36 + 6 + 27) in^2, or 69 in^2.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

yes
