I'm not sure what the answer can be for this
Find the volume of the rectangular prism.
V = lwh
V = (9)(16)(4)
V = 756 ft^3
Convert to cubic yards:
1 ft^3 = 0.037037037 yd^3
756 * 0.037037037 = 28
So there are 28 cubic yards of dirt he needs.
Multiply this to 25 to find the total cost of the dirt:
28 * 25 = 700
So the project will cost $700
I assume you need find out √28=√7*4=2√7
√150=√5*5*6=5√6
hope it helps
30° the angle is ro small to be 90° to small to be 60° and to small to be 120°
