What is the surface area of the box if it is scaled up by a factor of 10? the surface area is 432cm. leght 12cm. width 6cm. height 8cm

The scale factor for area is the square of the scale factor for linear dimensions. If linear dimensions are scaled up by a factor of 10, the area is scaled up by a factor of 10² = 100.

The area of the larger box is 100×432 cm² = 43,200 cm².

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
