Answer:
Step-by-step explanation:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)
The flag pole is 
or write it as 
tall.
Step-by-step Explanation:
Let "p" be the height of the flag pole.
The ratio of the child height to the pole height is the same as the ratios of their respective shadows, so,
Now, Cross multiply :-
→ 
→ 
→ 
This 
can be rounded off to 
as it ends with 
So, the flag pole is <u>9 metres</u> tall.
