Question

A company makes wax candles shaped like rectangular prisms. Each candle is 5cm long, 2cm wide, and 12cm tall. If the company used 5040cm3 of wax, how many candles did they make?

Answer 1

Answer:

The number of candles made by the company is 42.

Step-by-step explanation:

Given information: Each candle (rectangular prisms) is 5cm long, 2cm wide, and 12cm tall.

The volume of a rectangular prisms is

$V=l\times b\times h$

where, l is length, b is breadth and h is height.

The volume of each candle is

$V=5\times 2\times 12=120$

The volume of each candle is 120 cm³.

It is given that the company used 5040 cm³ of wax. We need to find the number of candle did the company make.

$\text{Number of candles}=\frac{5040}{120}$

$\text{Number of candles}=42$

Therefore the number of candles made by the company is 42.

Answer 2

Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120
,    ,=42candles
