To Find: The difference in the surface area of the large cube and the sum of the surface area of the small cubes.
Answer to Problem 42E
Explanation of Solution
Given:Eight cubes each with an edge of length one inch, are positioned together to create a large cube.
Area of one face of small cube=
Surface area of the small cube.
Area of the one face of the large cube=
Surface area of the larger cube
Surface area of all small cubes=
Difference in the surface area.
Thus correct option is

They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forwardAn airplane flies due west at an airspeed of 428 mph.
