1. Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid with base sides of 9 cm and the h
eight of the pyramid is 10 cm. Devin is using wax cubes with dimensions, 4 cm by 4 cm by 4 cm, to form the candle. How many whole wax cubes will Devin need to make the candle? Show your work.
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
He will need 527.52 cubic centimeters of wax. You divide the diameter by 2 ten multiply that number by itself to get the circumference. From there you multiply it by 12 then by 4 and there's your answer
