Volume = 8 cm3 so each side = 2 cm
So area of one face = 2cm * 2cm = 4 cm2
So total surface area (6 faces) = 6*4 cm2 = 24 cm2
216 cm3
If a cube has sides of length x cm then area = 6x2 cm2 and volume = x3 cm3
If the side is s cm long then the volume is s3 cm3. So s3 = 343 cm3 and therefore, s = 7 cm. Then the surface area is 6*s2 = 6*49 cm2 = 294 cm2
125 cm3
Total surface area = 864 cm2Area of each face = 1/6 of that = 144 cm2Length of the side of the cube = sqrt(144) = 12 cmVolume = 123 = 1,728 cm3
216 cm3
The cube's surface area is 54 cm2 and its volume is 27 cm3
1000 cm3=1L
V = 2.828 cm3
If a cube has sides of length x cm then area = 6x2 cm2 and volume = x3 cm3
SA = 294 cm2
A cube with 1 cm sides has a surface area of 6 cm2 and a volume of 1 cm3.
The total surface area of the cube is 294 cm2 The volume of the cube is 343 cm3
V = 34.837 cm3
SA = 213.7 cm2
V = 18.52 cm3
Example 6:A cube has a surface area of 150. What is the volume of the cube?Solution:The surface area of the cube is:SA= 6a2Thus:a2= SA/6 = 150/6 = 25anda = 5 cmThe volume of the cube is:V= a3V = 53V = 125 cm3
