Volume of a cube is length * width * height. Because it's a cube, all of these lengths are the same measurement so rather than doing V = l*w*h, we can do one of the measurements cubed, let's call it x.
So Volume = x³. So if we are given the volume, we can the length by doing the cube root.
∛125 = 5
∛216 = 6
Surface area of a cube = 6x². So now we plug both of these measurements into the formula.
For 5:
SA = 6(5)² = 6(25) = 150
For 6:
SA = 6(6)² = 6(36) = 216
The ratio of their surface areas is 150:216 or if you simplify it by dividing both by the GCF of 6, 25:36
Answer:
172 ft 2
Step-by-step explanation:
SA=2lw+2lh+2hw, for
A=2(lw + lh + hw)=2·(7 · 2+ 8 · 2 + 8 · 7)= 172 ft 2.
Hope this helps,
Best of Luck!
Answer:
The answer is 166.666667
Step-by-step explanation:
Okay so we need to find the number that we devide 20 to get 0.12 or 12% what I did was I put x as a varabile so
20/x=0.12
20=0.12x
20/0.12=x
x=166.666667
