Question

Can someone please HELP ME!!

I DONT UNDERSTAND
Aaron is making a candle by pouring melted wax into a mold in the shape of a cone. The radius of the base of the cone is 5 cm and the height of the cone is 9 cm. To get the wax for the candle, Aaron melts blocks of wax that are each 2 cm by 4 cm by 3 cm. How many of the wax blocks will Aaron need in order to make the candle? (Note: make sure you are showing the formulas you use to answer the question and how the numbers fit into the formulas).

Answer 1

Volume of a cone = PI x r^2 x h/3

Volume = PI x 5^2 x 9/3

Volume = 235.62 cubic cm.

Volume of a block of wax = L x W x H

Volume = 2 x 4 x 3 = 24 cubic cm.

Total number of blocks = Volume of cone / volume of blocks:

235.62 / 24 = 9.82

Round up to 10.

They will need 10 blocks.
