Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 13
Answer:
The container is filled with volume 1 L 862 mL,

Explanation:
Given rectangular tank has volume with dimensions 14 cm X 14 cm X 19 cm = 3,724 cm3,
Container is half-filled with oil so volume of oil in the container is
\(\frac{1}{2}\) X 3,724 cm3 = 1,862 cm3 = 1 L 862 mL.

Question 32.
A cubical tank whose edges each measure 1 2 centimeters is half-filled with water.
The water is poured into an empty rectangular tank measuring
10 centimeters by 8 centimeters by 7 centimeters until it is full.
How much water is left in the cubical tank? Give your answer in milliliters.
Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 14
Answer:
Water left in the cubical tank is  1,168 cm3,

Explanation:
Given a cubical tank whose edges each measure 1 2 centimeters is half-filled with water.
So volume with dimensions 12 cm X 12 cm X 12 cm = 1,728 cm3 and
the water is poured into an empty rectangular tank measuring
10 centimeters by 8 centimeters by 7 centimeters until it is full.
So water poured is 10 cm X 8 cm X 7 cm = 560 cm3 ,
therefore, water left in the cubical tank is 1,728 cm3 – 560 cm3 = 1,168 cm3.

Question 33.
The rectangular swimming pool shown contains 600 cubic meters of water.
How much more water has to be added so that the water level is 1 meter from the top?
Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 15
Answer:
Volume left in swimming pool is 4,900 cubic meters,

Explanation:
Given swimming pool contains volume of 50 m X 30 m X 3 m = 4,500 cubic meters
and the rectangular swimming pool shown contains 600 cubic meters of water.
and that the water level is 1 meter from the top is
4,500 cubic meters + 1 L = 5,500 cubic meters,
therefore, volume left in swimming pool is
5,500 cubic meters – 600 cubic meters = 4,900 cubic meters.

Question 34.
The rectangular tank shown is filled completely with water.
How much water must be taken out so the height of the water
level in the tank is 10 centimeters? Give your answer in milliliters.
Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 16
Answer:
Water to be taken out, so the height of the water
level in the tank is 10 centimeters is 240 cubic meters,

Explanation:
Given the rectangular tank shown is filled completely with water,
so, volume of 6 cm X 8 cm X 15 cm = 720 cubic meters,
The height of the water level in the tank is 10 centimeters,
so, volume of 6 cm X 8 cm X 10 cm = 480 cubic meters,
Water to be taken out is 720 cubic meters – 480 cubic meters = 240 cubic meters.

Question 35.
The large rectangular tank shown is \(\frac{4}{5}\)-filled with water.
The water is then poured into the smaller rectangular container until it is full.
How much water is left in the tank? Give your answer in liters and milliliters.
Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 17
Answer:
Water left in the tank is 1,920 cm3,

Explanation:
Given large rectangular tank has volume with dimensions 15 cm X 15 cm X 12 cm = 2,700 cm3,
The large rectangular tank shown is \(\frac{4}{5}\) filled with water
therefore tank has \(\frac{4}{5}\) X 2,700 cm3 =
\(\frac{4 X 2,700}{5}\) cm3 = 2,160 cm3.
The water is then poured into the smaller rectangular container until it is full.
Volume of smaller rectangular container with dimensions 6 cm X 5 cm X 8 cm = 2,40 cm3,
Water left in the tank is 2,160 cm3– 2,40 cm3= 1,920 cm3.

Question 36.
Water flows into this tank at 8 liters per minute. How long will it take to fill the tank?
Math in Focus Grade 5 Chapter 15 Practice 6 Volume of a Rectangular Prism and Liquid 18
Answer:
long it will take to fill the tank is 7.5 minutes,

Explanation:
Given rectangular tank has volume with dimensions
60 cm X 50 cm X 20 cm = 60,000 cm3 = 60 liters,
and Water flows into this tank at 8 liters per minute.
So long will it take to fill the tank is 60 liters ÷ 8 liters per minute = 7.5 minutes.
