if the ratio of the volume of two cubes is 1 : 8 , then find the ratio of the total surface area of the two cubes
1 answer:
Answer:
V = L^3 where v is volume and L the length of one side
A = 6 * L^2 total area of cube with side L
A = 6 * V^2/3 area of cube expressed in V
A2 / A1 = (V2 / V1)^2/3 6 cancels
A2 / A1 = 8^2/3 = 4 ratio of areas

Answer:
let x=2t and y=5t
-x+3y = -2t+15t = 13t
2x+y = 4t+5t = 9t
So the ratio is 13t : 9t
So, the ratio is 13 : 9
