Answer:
The term 2lw is independent of the height
Step-by-step explanation:
This formula is usually obtained reasoning like this: the rectangular prism has 6 faces, thus the surface area is the sum of the areas of these faces.
2 faces are l×w rectangles, so their area is lw+lw=2lw. Note that we are not using the height to compute the area, then this is the independent term.
The 4 remaining rectangles involve the height as one of their dimensions, so their areas (2hw+2lh) depend on the height.
we know that

of
is equal to find the
of the number 
so
Multiply
by the number 

therefore
<u>the answer is</u>

J = 3 because 3 is the only value given that is less than 4
Answer:
The volume of the box is 33.796 cubic inches
Step-by-step explanation:
Given

See attachment for the base of the prism
Required
The volume of the box
From the attachment, we have:
-- side length of the octagon
The area is then calculated as:

So, we have:



Evaluate the square root



The volume is then calculated as:


Answer:
Part A. He exercised for 1.5 hours.
60 + 30 = 1.5 hours.
Part B. Jacob spends 15 minutes doing freehand exercise.
Part C. No, because he spent 1.5 hours altogether.
