Answer:
The value of MA in third class lever is always less than one because the load arm is greater than the effort arm.
Step-by-step explanation:
As we know that when the load arm is greater than the effort arm, the mechanical advantage will always be lesser than one, which results in gain in speed.
The answer to this item is SOMETIMES. There are quotient of whole numbers that are also whole number such as that of 6 / 3 = 2. However, there exists a ratio between 4 and 3 which gives an answer of 4/3 or 1.33333.
i know a triangular prism has 5 faces and six vertices if that helps
Let
b-----------> the length side of the square box
h------------> the height of the box
SA---------> surface area of the box
we know that
[volume of the box]=b²*h
volume=256 in³
b²*h=256-------> h=256/b²-----> equation 1
surface area of the box=area of the base+perimeter of base*height
area of the base=b²
perimeter of the base=4*b
surface area=b²+(4*b)*h------> SA=b²+4*b*h-----> equation 2
substitute equation 1 in equation 2
SA=b²+4*b*[256/b²]-----> SA=b²+1024/b-----> SA=(b³+1024)/b
the answer is
the formula of the volume of the box is V=b²*h-----> 256=b²*h
the formula of the surface area of the box are
SA=b²+4*b*h
SA=(b³+1024)/b
