The surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²
<h3>Calculating surface area</h3>
From the question, we are to calculate the surface area of the rectangular prism
Surface area of a rectangular prism can be calculated by using the formula,
Surface area = 2(lw + lh + wh)
Where l is the length
w is the width
and h is the height
In the given diagram,
l = 21.5 mm
w = 4 mm
h = 5 mm
Putting the parameters into the equation, we get
Surface area = 2(21.5×4 + 21.5×5 + 4×5)
Surface area = 2(86 + 107.5 + 20)
Surface area = 2 × 213.5
Surface area = 427 mm²
Hence, the surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²

Answer:
C
−3.5×10×(−7)×(−18.5)
Step-by-step explanation:
There are three negative signs in this expression. An odd number of negative signs will result in a Negative product.
