Question

a company makes wax candles shaped like rectangular prisms. each candle is 4 cm long,3 cm wide, and 10cm tall. If the company used 4080 cm^3 of wax how many candles did they make

Answer 1

First, lets find the volume of a single candle:

$\begin{gathered} V=l\cdot w\cdot h \\ \Rightarrow V=(4)(3)(10)=12\cdot(10)=120 \\ V=120\operatorname{cm}^3 \end{gathered}$

now that we have the volume of one candle,we can divide the total wax to find how many candles the company can make:

$\frac{4080}{120}=34$

therefore, the company made 34 candles
