1 Dimensional Analysis
Grade 5 Worksheet Exercise 1
A cylindrical tank has a radius of 3 feet and a height of 8 feet. If 1 cubic foot equals 7.48 gallons, how many gallons of water can the tank hold? Use π ≈ 3.14.
Definition:

Dimensional analysis: Converting between different units using ratios and proportions.

Grade 5 Method:
  1. Calculate the volume of the cylinder: V = πr²h
  2. Convert cubic feet to gallons using the conversion factor
  3. Round to appropriate significant figures
  4. Express the final answer with units
Given
r = 3 ft, h = 8 ft
Formula
V = πr²h
Conversion
1 ft³ = 7.48 gal
Step 1: Calculate the volume of the cylinder

V = πr²h = 3.14 × 3² × 8 = 3.14 × 9 × 8 = 226.08 ft³

Step 2: Convert cubic feet to gallons

226.08 ft³ × 7.48 gal/ft³ = 1,691.08 gal

Step 3: Round to appropriate precision

≈ 1,691 gallons

Step 4: Express with proper units

The tank can hold 1,691 gallons of water

Final answer:

The cylindrical tank can hold approximately 1,691 gallons of water.

Grade 5 Rules:

• Volume formula: V = πr²h for cylinders

• Dimensional analysis: Multiply by conversion factor

• Significant figures: Round appropriately

2 Rate and Time Problem
Grade 5 Worksheet Exercise 2
Water flows into a tank at a rate of 2.5 gallons per minute. How many hours will it take to fill a 15,000-gallon tank? Express your answer in hours and minutes.
Definition:

Rate-time problem: Calculating time based on flow rate and total capacity.

Rate
2.5 gal/min
Total
15,000 gal
Time
? hours
Step 1: Calculate time in minutes

Time = Total ÷ Rate = 15,000 gal ÷ 2.5 gal/min = 6,000 minutes

Step 2: Convert minutes to hours

6,000 min ÷ 60 min/hour = 100 hours

Step 3: Express in hours and minutes

100 hours = 100 hours and 0 minutes

Step 4: Verify the calculation

100 hours × 60 min/hour × 2.5 gal/min = 15,000 gal ✓

Final answer:

It will take 100 hours to fill the 15,000-gallon tank.

Grade 5 Rules:

• Rate formula: Time = Total ÷ Rate

• Unit conversion: 60 minutes = 1 hour

• Verification: Check your calculations

3 Density and Capacity
Grade 5 Worksheet Exercise 3
A rectangular container measures 12 inches by 8 inches by 6 inches. If 1 cubic inch of water weighs 0.036 pounds, what is the weight of the water when the container is completely filled?
Definition:

Density: Mass per unit volume, relating volume to weight.

Dimensions
12×8×6 in
Volume
l×w×h
Density
0.036 lb/in³
Step 1: Calculate the volume of the container

Volume = length × width × height = 12 × 8 × 6 = 576 in³

Step 2: Calculate the weight of water

Weight = Volume × Density = 576 in³ × 0.036 lb/in³ = 20.736 lb

Step 3: Round to appropriate precision

≈ 20.7 pounds

Step 4: Express with proper units

The weight of water when the container is full is 20.7 pounds

Final answer:

The water in the completely filled container weighs 20.7 pounds.

Grade 5 Rules:

4 Complex Rate Problem
Grade 5 Worksheet Exercise 4
Two pipes fill a tank. Pipe A fills at 3 gallons per minute, Pipe B fills at 5 gallons per minute. If the tank holds 2,400 gallons, how long will it take to fill the tank if both pipes work together? Express your answer in hours and minutes.
Definition:

Combined rate: Adding individual rates to find total rate of work.

Pipe A
3 gal/min
Pipe B
5 gal/min
Combined
8 gal/min
Step 1: Calculate combined rate

Total rate = 3 gal/min + 5 gal/min = 8 gal/min

Step 2: Calculate time to fill

Time = Total ÷ Rate = 2,400 gal ÷ 8 gal/min = 300 minutes

Step 3: Convert minutes to hours

300 min ÷ 60 min/hour = 5 hours

Step 4: Express in hours and minutes

5 hours and 0 minutes

Final answer:

It will take 5 hours to fill the tank with both pipes working together.

Grade 5 Rules:

• Combined rates: Add individual rates together

• Time calculation: Time = Total ÷ Combined rate

• Unit conversion: 60 minutes = 1 hour

5 Advanced Real-world Problem
Grade 5 Worksheet Exercise 5
A conical water tank has a base radius of 5 feet and a height of 12 feet. If water is being pumped out at a rate of 10 gallons per minute, how long will it take to empty the tank when it's full? (Volume of cone = 1/3πr²h)
Definition:

Conical volume: Calculating capacity of conical containers using geometric formulas.

Given
r=5ft, h=12ft
Formula
V=1/3πr²h
Rate
10 gal/min
Step 1: Calculate the volume of the cone

V = 1/3πr²h = 1/3 × 3.14 × 5² × 12 = 1/3 × 3.14 × 25 × 12 = 314 ft³

Step 2: Convert cubic feet to gallons

314 ft³ × 7.48 gal/ft³ = 2,348.72 gal ≈ 2,349 gal

Step 3: Calculate time to empty

Time = Volume ÷ Rate = 2,349 gal ÷ 10 gal/min = 234.9 min

Step 4: Convert to hours and minutes

234.9 min = 3 hours and 54.9 minutes ≈ 3 hours and 55 minutes

Final answer:

It will take approximately 3 hours and 55 minutes to empty the conical tank.

Grade 5 Rules:

• Conical volume: V = 1/3πr²h

• Dimensional analysis: Convert units using conversion factors

• Rate problems: Time = Volume ÷ Rate
