Pi*3^2= 9pi
pi*6=6pi
6pi*17= 102pi
102pi+9pi= 111pi in. squared
pi*6^2=36pi
pi*12=12pi
36pi+12pi*x=111pi
12pi*x=75pi
x=6.25pi
x=Height btw
Answer:
27x plus 66
Step-by-step explanation:
divide the 27 into the 66
So hmm notice the picture below
a rectangular prism, is just 6 rectangles stacked up to each other
so... to find the Surface Area, just get the area of each rectangle, notice is 3 pairs of similar rectangles, so, get their area and sum them up, that's the Surface Area of the rectangular prism
now, the Lateral Area, is just the area of the sides, laterals, so, that means, just get add up the areas of the rectangles upfront, on the back, and the ones on left and right sides, that's the Lateral Area of the rectangular prism.
