Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4Ratio of sides = 10/5 = 2 So ratio of surface area = 22= 4
a. 2 to 5.
To obtain the ratio of surface area to volume, divide the surface area by the volume.
1mm cube has volume of 1mm3 and a surface area of 6*(1*1) = 6mm²2mm cube has a volume of 8mm3 and a surface area of 6(2*2)=24mm²Ratio for 1mm cube is 6-1 and ratio for 2mm cube is 3-1 ■
This is pretty easy, just divide 432 by 864 and you get a 1:2 ratio.
