Question
The approximate change in the volume of a cube of side x metres caused by increasing the side by 3% is
A. 0.06 x3 m3
B. 0.6 x3 m3
C. 0.09 x3 m3
D. 0.9 x3 m3
Solution
The volume of a cube (V) of side x is given by V = x3.
Hence, the approximate change in the volume of the cube is 0.09x3 m3.
The correct answer is C.
