Answer:
V = x(19-2x)(4-2x)
Step-by-step explanation:
We are given;
Length of flat piece of material =19 inches
Width of flat piece = 4 inches
We are told that the open box is to be made from a flat piece by cutting equal squares of length x from the corners and folding up the sides
Thus, we will now have;
length of open box = (19-2x) inches
Width of open box = (4-2x) inches
Height of box = x inches
We know that: Volume of box = length × width × height
So, plugging in the relevant values, we have;
Volume of box(V) = x(19-2x)(4-2x)
A. +60
B. +80
C. + 742
D. -919
The surface area is the area of one of the cube's faces. The volume, however is how much of something could fit inside of the cube.
According to the solving the displacement of the block is:
= 40m
<h3>What does force-displacement mean?</h3>
A shift inside of an object's position is referred to as "displacement." It has a magnitude and a direction, making it a vector quantity. An arrow pointing from of the starting point to the finishing point serves as its symbol. For instance, an object's position changes if it moves from position A to position B.
<h3>Why is there a shift in the workforce?</h3>
The scalar product of displacement and force is equivalent to work. The cosine of the angle between two vectors is added to their lengths to form the scalar product of the two vectors. Work is defined as the product of force, displacement, and the sine of the angle formed by the force's and displacement's directions.
<h3>According to the given data:</h3>
The formula for work is W=F × d.
Work done = 80J
Force = 20N
Displacement = ?
So,
W=F × d.
80 = 20 x d
d = 80/20
d = 40 m
According to the solving the displacement of the block is:
= 40m
