Q. If volume of cube is 4913cm3 then length of side of cube is
Let side be 'a'
volume of a cube=a3
a3 = 4913
a = 17cm
Number 343 is cube of
If length of one side of cube is 20cm then volume of cube must be
Volume of cube = a3
Given that side of a cube is 20cm
Then volume will be (20cm)3
Volume = 8000 cm3
93 (cube of 9) is equal to
Cubic root of 729 is
An integer is divisible by 9 if and only if the sum of its digits is divisible by 9.
The sum of the digits of 729 is 7 + 2 + 9 = 18 and 18 is divisible by 9 so 729 is divisible by 9.
Hence, the correct answer is Option D
