Monica is making a candle by pouring melted wax into a mold in the shape of a cylinder. The radius of the cylinder’s base is 6 cm, and the height of the cylinder is 12 cm. To get the wax for the candle, Monica melts cubes of wax that are each 5 cm by 5 cm by 5 cm. How many of the wax cubes will Monica need to purchase to make the candle? (Note that Monica is not able to purchase partial

cubes). Show all your work

Answer 1

Volume of the cylinder=3.14×6×6×12=1356.48

volume of one cube=5×5×5=125

divide1356.48÷125=10.85

since she can't buy partial cubes, she'll have to purchase 11 cubes
