Answer:
The expression 7x represents the height of the container.
Step-by-step explanation:
From the question:
We are being informed that; if the length of the container is half of a foot longer than its width.
Let the width be x;
Then the length of the container can now be ; x+1/2
We all known that the volume of a rectangular prism is : V= l×w×h
here;
l = length
w = width
h = height
If we rewrite the given expression :
;
Then we factor we make a similar coefficient of the above equation, the remaining entities left in the parenthesis should be a linear term with a leading coefficient of 1 to match the expression for the length of the container.
i.e
Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
Answer:
Part a) The volume of the original pyramid is
Part b) The volume of the pyramid increases by
Step-by-step explanation:
<u><em>The complete question is</em></u>
Part 1) The volume of the pyramid shown in the figure is 9,15,21, or 63 cubic centimeters?. Part 2) If the slant height of the pyramid increases by 4 centimeters and its height increases by 2 centimeters, the volume of the pyramid increases by 6,9,12 or 21 cubic centimeters?
we know that
The volume of the pyramid is equal to
where
B is the area of the base
h is the height of pyramid
see the attached figure to better understand the problem
Step 1
Find the volume of the original pyramid
the area of the base B is equal to
substitute
Step 2
Find the volume of the new pyramid
-------> the area of the base is the same
------> the height increase by
substitute
Subtract the original volume from the new volume
