Question

what is the surface area of the box if it is scaled up by a factor of 10? surface area is 164, height is 4 in, width is 3 in, length is 10 in.

Answer 1

16,400 in²

Explanation:

Ratio of Areas = (Ratio of sides)²

A/164 = 10²

A/164 = 100

A = 16400

Answer 2

16400 in ^2

Explanation:

For area, we multiply by the scale factor squared

area 2 = sf^2 * area 1

Since the scale factor is 10,

area 2 = 10^2* 164

= 100*164

= 16400
