Can u please help with part b the answer is not 11. I'll pick the BEST ONE

The two cubed numbers are 64 and 27
3 x 3 x 3 = 27
4 x 4 x 4 = 64
you take these two numbers and subtract them, making the difference 37
Answer:
a) 48
b) 37
Step-by-step explanation:
a)
okay so the difference between the two square numbers present here
the two square numbers present are -
(multiply 8 twice you'll get 64, same for 16)
so calculating their difference would be easy
= 64 - 16
= 48
b)
now, the difference between two cube numbers
the only cube numbers that exist in this series are 27 and 64 (once again)
(multiply 4 thrice you'll get 64)
now, calculating their difference
= 64 - 27
= 37
