McGraw-Hill Math Grade 5 Answer Key Chapter 10 Lesson 13 Problem Solving: Using Formulas
Solve. Use the formulas V= (l × w) × h, V = B × h, or A = l × w if necessary.
A large fish pond is 5 meters long, 4 meters wide, and 12 centimeters deep. What is the volume of the pond in centimeters?
A rectangular pool has a base area of 600 ft2. The total volume of the pool is 4,800 ft3. How deep is the pool?
Given rectangular pool,
Area of base (b) = 600 ft2
Total volume of the pool (v) = 4,800 ft3
Deep of the pool (h)= ?
v = b x h
4,800 ft3 = 600 ft2 x h
4,800 ft3/600 ft2 = h
8 feet = h
The pool is 8 feet deep.
A store sells dragon figures in 10-inch cube boxes. How many boxes of figures can fit on a shelf that is 30 inches long, 20 inches high, and 30 inches wide?
Dylan covers the rectangular floor of his room with 24 square meters of carpet The length of the room is 6 meters. What is the width of the room?
Area of the rectangular floor (A)= 24 square meters
Length of the room (l) = 6 meters
Width of the room (w) = ?
A = l x w
24 m2 = 6 m x w
24 m2 /6 m= w
4 m = w
Width of the room is 4 meters.

How much greater in volume is the backpack than the tote?
Volume of Tote (V) = 16 in x 15 in x 12 in = 2,880 in3
Volume of Backpack (V) = 20 in x 15 in x 10 in = 3,000 in3
3,000 in3 – 2,800 in3 = 120 in3
The volume of backpack is 120 in3 greater than the tote.
