The previous rectangular prism had a surface area of 254 square inches. if each dimension is doubled, how does the surface area change?
the surface area doubles.
the surface area triples.
the surface area increases by 4 times.
the surface area increases by 8 times.

The surface area increases by 4 times

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the surface area of the new rectangular prism

y ---> the surface area of the original rectangular prism

so

we have

----> because is doubled

substitute and solve for x

----> surface area increases by 4 times.

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

answer: .75 km
