Two forces act at a point in the plane. The angle between the two forces is given. Find the magnitude of the resultant force. forces of 109 and 98 lb, forming an angle of 113° 24'

The correct answer is 7

The correct answer is b

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
