Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 9 cm and the height of the pyramid is 10 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? SHOW YOUR WORK.

Step-by-step explanation:

Pyramid mold

volume of a square based pyramid =

(where a is the side of the base and h is the height)

Given a = 9 and h = 10:

volume = = 270 cm³

Wax Cube

volume of a cube = a³

(where a is the length of one edge)

Given a = 4

volume = 4³ = 4 x 4 x 4 = 64 cm³

Divide the volume of the pyramid by the volume of 1 wax cube:

270 ÷ 64 = 4.21875

We need to round this number up to 5 as if we rounded down to 4, we wouldn't have quite enough to fill the pyramid.

Therefore, Devin will need 5 wax cubes in order to make the candle.

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
