Question

the measurements of a box are doubled. what happens to its surface area?

Answer 1

Answer:

Surface area increases by a factor of 4

Step-by-step explanation:

Given the linear ratio = a : b, then

the area ratio = a² : b²

Here the linear ratio = 1 : 2, hence

area ratio = 1² : 2² = 1 : 4 ← increase by factor of 4
