Step-by-step explanation:
The length, breadth and height of the solid is not equal, so it's a cuboid
Volume of a cuboid is calculated by productoflength,breadthandheighti.e. V = lbh
Puttingthevaluesintheformula,
=> Volume = 1m * 2m * 2m
=> Volume = 4m3 (Option 3)

Answer:
B) 44
Step-by-step explanation:
54 - 49 = 5
39 - 34 = 5
49 - 5 = 44
The amount of work required to stretch 9 inches beyond the natural length will be 4.5 ft-lb
Given data:
To determine the work required to stretch the spring 9 inches beyond its natural length, use the concept of Hooke's Law.
Hooke's Law states that the force required to stretch or compress a spring is directly proportional to the displacement from its equilibrium position.
Given that stretching the spring by 2 ft requires 12 ft-lb of work, determine the constant of proportionality.
The constant of proportionality (k) represents the stiffness of the spring and can be calculated using the formula:
k = work / displacement
k = 12 ft-lb / 2 ft
k = 6 lb/ft
Now, calculate the work required to stretch the spring 9 inches (0.75 ft) beyond its natural length using the same constant of proportionality:
work = k * displacement
work = 6 lb/ft * 0.75 ft
work = 4.5 ft-lb
Hence, it would require 4.5 ft-lb of work to stretch the spring 9 inches beyond its natural length.
