If the volume of a cube is given as 12167cm
3
, then the surface area of the cube will be:
- A3475 cm
- B4574 cm
- C3174 cm
- D5413 cm
Solution & Step-by-step Explanation
Let the edge length of the cube be acm.
The formula for the volume (V) of a cube is:
V=a
3
Given that V=12167cm
3
:
a
3
=12167
a=
3
12167
=23cm
(Since 20
3
=8000 and 30
3
=27000, and the last digit is 7, the number must be 23).
The formula for the total surface area (TSA) of a cube is:
TSA=6a
2
Substitute the value of a=23:
TSA=6×(23)
2
TSA=6×529=3174cm
