The number of cubes that Devin will need to make will be given by:
(volume of each pyramid wax)/volume of cube
volume of cube=length*width*height
=4×4×4
=64 cm³
volume of the candle=1/3π*(base area)*h
=1/3×(9×9)×10
=270 cm³
number of cubes needed
270/64
=4.21875~4.23 cubes
Answer: The correct option is
(D) 60.
Step-by-step explanation: Given that the number of stamps that Kaye and Alberto had were in the ration of 5:3 respectively.
After Kaye gave Alberto 10 of her stamps, the ration of the number of Kaye had to the number of Alberto had was 7:5.
We are to find the number of stamps that Kaye had more than Alberto.
Let the number of stamps Kaye and Alberto has are 5x and 3x respectively.
Then, according to the given information, we have

So, the number of stamps that Kaye had = 5 × 30 = 150
and
the number of stamps that Alberto had = 3 × 30 = 90.
Therefore, the number of stamps that Kaye had more than Alberto is

Thus, Kaye had 60 stamps more than Alberto.
Option (D) is CORRECT.
