Whats the surface area of the rectangular if it is scaled up by a factor of 10?

Question

Length: 3 feet
Width: 6.5 feet
Height: 8 feet

Answer 1

Surface Area = 2lw + 2lh + 2wh

Original surface area = 2(3)(6.5) + 2(3)(8) + 2(6.5)(8) = 39 + 48 + 104 = 191 square feet

Scaled up dimensions:
Length: 3 feet x 10 = 30 feet
Width: 6.5 feet x 10 = 65 feet
Height: 8 feet x 10 = 80 feet

Scaled up surface area = 2(30)(65) + 2(30)(80) + 2(65)(80) = 3900 + 4800 + 10400 = 19100 square feet

Therefore, the surface area of the rectangular prism scaled up by a factor of 10 is 19100 square feet.
