Paula designed a garden bed in the shape of an irregular prism. It took 5 cubic feet of dirt to cover the bed to a depth of 6 inches. How much area does her garden bed cover in square feet?​

9 x 8 divided by (5-3)=36

answer: 1 + 1 = 11

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
