Question

One cubic foot of water equals approximately 7.5 gallons. A rectangular restaurant sink holds 50.4 gallons of water. It has a length of 3 ft and a height of 1.4 ft. What is the volume of the sink? What is the width of the sink?

Answer 1

1 cm³ = 7.5 gallons

----------------------------------------------------------
Find 50.4 gallons in cm³:
----------------------------------------------------------
50.4 ÷ 7.5 = 6.72 cm³

----------------------------------------------------------
Formula:
----------------------------------------------------------
Volume = Length x Width x Height

----------------------------------------------------------
Find Width:
----------------------------------------------------------
6.72 = 3 x 1.4 x Width

6.72 = 4.2 x Width

Width = 6.72 ÷ 4.2

Width = 1.6 ft

----------------------------------------------------------
Answer: The width of the sink is 1.6 feet.
