Option A
The width of the rectangular prism is 13 units less than the length
Solution:
Given that, the length, width, and height of a rectangular prism is a, (a-13), and (a+13) respectively
From given question,
Length of rectangular prism = a
Width of rectangular prism = a - 13
Height of rectangular prism = a + 13
We have to find which statement best describes (a - 13)
From given (a - 13) means Width of rectangular prism
Therefore,
Width of rectangular prism = (a - 13)
We know that from given "a" denotes Length of rectangular prism
So we get,
Width of rectangular prism = (Length of rectangular prism - 13)
So the above expression means that width is 13 units less than length
So option A is correct. The width of the rectangular prism is 13 units less than the length
Let us also analyse the options one by one
a.) the width of the rectangular prism is 13 units less than the length
Which is written mathematically as,
width = length - 13 = a - 13
So this option is correct
b. the height of the rectangular prism is 13 units more than the length
Which is written mathematically as,
height = 13 + length = 13 + a
So this option does not describes (a - 13)
c. the width of the rectangular prism is 13 units less than the height
Which is written mathematically as,
width = height - 13 = a + 13 - 13 = a
So this option does not describes (a - 13)
d. the length of the rectangular prism is 13 units less than the height
Which is written mathematically as,
length = height - 13 = a + 13 - 13 = a
So this option does not describes (a - 13)
