What is the surface area of the refrigerator if it is scaled up by a factor of 10?

Question

The refrigerator’s length is 3 ft and its width is 6.5 and it’s hieght is 8 ft

Answer 1

To find the surface area of the scaled-up refrigerator, we first need to scale up the dimensions by a factor of 10.

Scaled-up length = 3 ft * 10 = 30 ft
Scaled-up width = 6.5 ft * 10 = 65 ft
Scaled-up height = 8 ft * 10 = 80 ft

Now, we calculate the surface area of the scaled-up refrigerator:

Surface Area = 2*(Length*Width + Length*Height + Width*Height)
Surface Area = 2*(30*65 + 30*80 + 65*80)
Surface Area = 2*(1950 + 2400 + 5200)
Surface Area = 2*(9550)
Surface Area = 19100 square feet

Therefore, the surface area of the refrigerator if it is scaled up by a factor of 10 is 19100 square feet.
