Question

What is the surface area of the rectangular prism? 480mm 427mm 213.5mm 255mm

Answer 1

The surface area of the rectangular prism is 427 mm². The correct option is the second option 427 mm²

Calculating surface area

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
