The prism has a surface area of 202 ft2. What would the surface area of the prism be if each dimension were tripled?
In the previous problem, we dealt with volume. When the side doubled (x 2), the volume became 216/27 = 8 times bigger. When the side became 2 times larger, the volume became 2^3 times larger. With area, when the side increases by k times, the area increases by k^2 times.
202/2
Once again. In two figures, if the scale factor is k, the volume becomes k^3 times the original volume. The area becomes k^2 times the original area.
so you times all the sides and then add them
The original area here is 202 ft^2. The scale factor is 3. That is what tripling means. That means the area becomes 2^2 times larger than it was.
gtg i'll be back in about 15-20 minutes
so 202*2 right?
ah okay
here is a good way to look at it
lets say the prism has dimensions w,L,h, for width length and height
ok
is it 1818???
look at one of the rectangular sides |dw:1429811814487:dw|
