Idon’t understand ! can someone explain it to me? asap! you all even if you don’t know how to do it

615.6

Step-by-step explanation:

First find the number of cubic feet.

V = B * h

B is a triangle with a right angle on your left and two 6 foot lengths on each leg.

Area = 1/2 b * h

b = 6 feet

h = 6 feet

Area = 1/2 * 6 * 6 = 18 square feet.

The volume = B * h

h = 11.4

B = 18 sq ft

Volume = 18 * 11.4

Volume = 205.2 Cubic Feet.

Each cubic foot costs 3.00 dollars

Cost = volume * cost/cu foot

Cost = 205.2 * 3

Cost = 615.6

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
