**Solving multi step problems worksheet :**

Worksheet on solving multi step problems is much useful to the students who would like to practice solving word problems.

1. The classroom aquarium holds 30 gallons of water. It is 0.8 feet wide and has a height of 2 feet. Find the length of the aquarium. Use the fact that one cubic foot of water contains about 7.5 gallons of water.

2. An aquarium holds 33.75 gallons of water. It has a length of 2 feet and a height of 1.5 feet. What is the width of the aquarium ? Use the fact that one cubic foot of water contains about 7.5 gallons of water.

**Problem 1 : **

The classroom aquarium holds 30 gallons of water. It is 0.8 feet wide and has a height of 2 feet. Find the length of the aquarium. Use the fact that one cubic foot of water contains about 7.5 gallons of water.

**Solution : **

From the given information, we have

**Step 1 : **

Find the volume of the classroom aquarium in cubic feet.

That is,

= 30 gallons / 7.5 gallons per cubic foot

= 4 cubic feet

(There are 7.5 gallons in 1 cubic foot. Divide to find how many groups of 7.5 gallons are in 30 gallons)

**Step 2 :**

Find the length of the aquarium.

Use the formula V = lwh to write an equation.

4 = l x 0.8 x 2

4 = l x 1.6

Divide both sides of the equations by 1.6

4/1.6 = (l x 1.6) / 1.6

2.5 = l

Hence, the length of aquarium is 2.5 feet

**Problem 2 :**

An aquarium holds 33.75 gallons of water. It has a length of 2 feet and a height of 1.5 feet. What is the width of the aquarium ?

(Use the fact that one cubic foot of water contains about 7.5 gallons of water.)

**Solution : **

From the given information, we have

**Step 1 : **

Find the volume of the classroom aquarium in cubic feet.

That is,

= 33.75 gallons / 7.5 gallons per cubic foot

= 4.5 cubic feet

(There are 7.5 gallons in 1 cubic foot. Divide to find how many groups of 7.5 gallons are in 33.75 gallons)

**Step 2 :**

Find the width of the aquarium.

Use the formula V = lwh to write an equation.

4.5 = 2 x w x 1.5

4.5 = 3 x w

Divide both sides of the equations by 3

4.5/3 = (3 x w) / 3

1.5 = w

Hence, the width of aquarium is 1.5 feet
