The volume of any cube is (length of one side)3The surface area is (length of one side)2 x 6 [since a cube has six sides]
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
Cube root of 216 = 6 units Therefore each face is 6*6 units which = 36 square units A cube has 6 faces, so 6*36 = 216 square units which is the surface area of the cube.
Surface area = 6s2, volume = s3
To tackle this you first need to know the equations for both volume and surface area. The surface area of a cube is 6x2 where x is the side length. The volume of the cube is x3. Thus x is the cube root of the volume. We can substitute this in to the surface area equation and say that the surface area of a cube is 6volume2/3 This can also be rearranged to say that the volume of the cube is (the surface area/6)1.5
The surface area of a cube whose volume is 64 cubic units is: 96 square units.
The surface area of a cube whose length is 4.7 is 132.5 units squared.
The cube's volume is 1728cm3
1728cm3
For volume of a cube, V=S3 For surface area, A=6S2 S is the length of one side.
The surface area is 6*52 = 150 sq metres.
The total surface area is 230.64 square units.
216 square inches
96
384.5 units squared.
A cube has six faces. Therefore, its surface area is 6 times a face's area.The area of a square whose edges measure 9 cm is 81 cm2.Therefore, the surface area of a cube whose edges measure 9 cm is 6*81 = 486 cm2.
V = 343 units cubed.
