Q.1 A matchbox measures 4 cm × 2.5 cm × 1.5 cm. What will be the volume of a packet containing 12 such boxes?
Ans
Volume of a matchbox = 4 cm × 2.5 cm × 1.5 cm
= 15 cm3
Volume of a packet = Volume of 12 matchboxes
= 12 x 15 cm3
= 180 cm3
Thus, the volume of a packet containing 12 matchboxes is 180 cm3.
Q.2 A cuboidal water tank is 6 m long, 5 m wide and 4.5 m deep. How many litres of water can it hold? (1 m3 = 1000 l)
Ans
Volume of cuboidal water tank = 6 x 5 x 4.5 m3
= 135 m3
Since, 1 m3 = 1000 litres
So, volume of water in tank = 135 x 1000 litres
= 135000 litres
Q.3 A cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380 cubic metres of a liquid?
Ans
Q.4 Find the cost of digging a cuboidal pit 8 m long, 6 m broad and 3 m deep at the rate of Rs 30 per m3.
Ans
Volume of cuboidal pit = 8 x 6 x 3
= 144 m3
Cost of digging 1 m3 pit = Rs. 30
Then, the cost of digging cuboidal pit
= Rs. 30 x 144
= Rs. 4320
Thus, the cost of digging a cuboidal pit is Rs. 4320.
Q.5 The capacity of a cuboidal tank is 50000 litres of water. Find the breadth of the tank, if its length and depth are respectively 2.5 m and 10 m.
Ans
Capacity of cuboidal tank = 50,000 litres
Length of cuboidal tank = 2.5 m
Depth of cuboidal tank = 10 m
Let breadth of cuboidal tank = p m
Since, 1000 litres = 1 m3
So, 50,000 litres = 50 m3
Then, Volume of tank = lbh
50 m3= 2.5 x p x 10
p = 2 m
Thus, the breadth of the tank is 2 m.
Q.6 A village, having a population of 4000, approximately requires 150 litres of water per head per day. It has a tank measuring 20 m × 15 m × 6 m. For how many days will the water of this tank last?
Ans
Volume of water tank = 20 m × 15 m × 6 m
= 1800 m3
= 1800000 litres
[Since, 1 m3 = 1000 litres]
Water require for a person = 150 litres
Water require for 4000 persons
= 150 x 4000 litres
= 600000 litres
Number of days to last the water of this tank
= (1800000/600000) days
= 3 days
Thus, the water of tank will last in 3 days in a village of 4000 people.
Q.7 A godown measures 40 m × 25 m × 15 m. Find the maximum number of wooden crates each measuring 1.5 m × 1.25 m × 0.5 m that can be stored in the godown.
Ans
Q.8 A solid cube of side 12 cm is cut into eight cubes of equal volume. What will be the side of the new cube? Also, find the ratio between their surface areas.
Ans
Q.9 A part of a river 3 m deep and 40 m wide is flowing at the rate of 2 km per hour. How much water will fall into the sea in a minute?
Ans
