The height of the rectangular prism is 5 cm
The rectangular prism has a base area of 16 cm².
<h3>Volume of rectangular prism;</h3>
Therefore,
V = 16h
where
h = height of the rectangular prism
Another box has a volume of 320 cm³ and holds 4 of the rectangular prism with no extra space.
Therefore,
4(16h) = 320
64h = 320
divide both sides by 64
64h / 64 = 320 / 64
h = 5
Therefore, the height of the rectangular prism is 5 cm

Expression for perimeter is 2(14-x + x) = 28
<u>Step-by-step explanation:</u>
Step 1:
Given expression for area of the rectangle = a(x) = x(14-x) where x is the width. Then length = 14-x since area = length × width
Step 2:
Find expression for perimeter of the rectangle.
Perimeter of the rectangle = 2(length + width) = 2(14 - x + x) = 2 × 14 = 28
