Solved Questions on Capacity
1. If a red drum can hold 10 gallons of water, a blue drum can hold 7 gallons of water and a green drum can hold 5 gallons of water, then what is the total capacity of all the drums given below?
a) 31 gallons
b) 41 gallons
c) 51 gallons
d) 61 gallons
Answer: c) 51 gallons
Explanation: Capacity of the water in a red drum = 10 gallons
Total capacity of the water in 2 red drums = 2 × 10 = 20 gallons
Capacity of the water in a blue drum = 7 gallons
Total capacity of the water in 3 blue drums = 3 × 7 = 21 gallons
Capacity of the water in a green drum =5 gallons
Total capacity of the water in 2 green drums = 2 × 5 = 10 gallons
The total capacity of all the drums = 20 + 21 + 10 = 51 gallons
2. If each cup can hold 2 pints of tea, then what is the total capacity of the cups in quarts given below?
a) 4 quarts
b) 8 quarts
c) 12 quarts
d) 16 quarts
Answer: b) 8 quarts
Explanation: Capacity of a cup of tea = 2 pints
Total capacity of 8 cups of tea = 8 × 2 = 16 pints
Total capacity of 8 cups of tea in quarts = 16 ÷ 2 = 8 quarts.
3. If a coke bottle contains 200 mL, then what is the total capacity of coke?
a) 1 L 400 mL
b) 1 L 600 mL
c) 1 L 800 mL
d) 2 L
Answer: b) 1 L 600 mL
Explanation: Capacity of a coke bottle = 200 mL
Total capacity of 8 coke bottles = 8 × 200 mL
= 1600 mL
= 1000 mL + 600 mL
= 1 L+ 600 mL
= 1 L 600 mL
4. A car can travel a distance of 10 km with 500 ml of petrol. How much petrol will the car need to cover 100 km?
a) 5 litres
b) 8 litres
c) 10 litres
d) 15 litres
Answer: a) 5 litres
Explanation: petrol needed by car to cover 10 km = 500 mL
petrol needed by car to cover 1 km = 500 ÷ 10 = 50 mL
petrol needed by car to cover 100 km = 50 x 100 = 5000 mL
= 5000 ÷ 1000
= 5 litres
5. A jar contains 2800 mL of milk. If 625 mL is poured out into the glass, how many litres and millilitres of milk is left in the jar?
a) 2 L 75 mL
b) 2 L 175 mL
c) 2 L 275 mL
d) 2 L 375 mL
Answer: b) 2 L 175 mL
Explanation: Capacity of milk in jar = 2800 mL
Capacity of milk poured into the glass = 625 mL
Capacity of milk left in the jar = 2800 − 625
= 2175 mL
= 2000 mL + 175 mL
= 2 L + 175 mL
= 2 L 175 mL
