Question

Hello I need some help I'm doing something wrong on this

Answer 1

Given:

Surface Area = 14100 mm²

10mm = 1cm

Required:

Surface Area in cm²

Step-by-step explanation:

The given surface area is 14100 mm²

And 10mm = 1cm

So, to convert a smaller unit into bigger unit we divide the smaller unit with the conversion

But here units are in square so the conversion will be

1 cm² = 100 mm²

`\begin{gathered} A=14100mm^2 \\ \\ 10mm=1cm \\ 100mm^2=1cm^2 \\ A=(14100)/(100)=141cm^2 \end{gathered}`

Final answer:

Surface area in cm² is 141.
